Crown Sensitivity: Causes and Management

Crown Sensitivity: Causes and Management

Losing a tooth to infection (decay) or trauma can be a painful experience. Imagine that you are in a dental chair and just got a new tooth or a bridge fitted. It is a joyous experience, almost like a new found lease of life, to be able to eat better and look better. However, even after a few days to a week, you realize that the new crown is just not settling down completely. There is a constant sensitivity that exists and is not allowing you to enjoy the new tooth.  

There are various reasons that the new crown can be sensitive, some of them including:

  1. A high point: On the new crown, there could be small points that do not allow for a bite as earlier. This can lead to sensitivity and minor jaw discomfort. 
  2. Improper fit with exposed dentin: This can happen at the neck area, where the crown is not fitting the tooth, leaving a small part of dentin exposed. This can lead to sensitivity once the crown is fixed in.
  3. Other decayed teeth: If there is a decayed tooth adjacent to the crown, it could be confusing and sometimes difficult to pinpoint the exact area.

If it persists for more than a week, check with your dentist on the following:

  1. Severity of decay: The extent of decay in the first place should be considered, especially if you have had crown as a result of extensive tooth decay. If it was involving a large portion of the dentin, the changes of having sensitivity are high, even after a crown placement.  In these cases, there could be silent abscess, which may never manifest as symptoms, but can cause a gnawing sensitivity issue with each bite.
  2. Area of decay: Root caries and cervical caries are more prone to have sensitivity compared to the crown of the tooth. The enamel layer in these areas is thin and the chances of dentinal involvement is high. The rate at which the decay will reach the pulp and cause pain is also higher.
  3. Type of dental treatment: If extensive metal work is done, the sensitivity might last longer than a week, which is the norm.
  4. Triggering factors: Make a note of what triggers the sensitivity, hot, cold or sweets. 
  5. Management: As mentioned, expect the sensitivity with your new crown to last for up to a week. In some cases, it may be longer, depending on, as noted above, the severity of the original decay, the area, triggers, etc. 

While some cases may be managed with a small trim of the crown, some may need the crown to be re-fitted, and some may even require re-treating the tooth completely.

Soft drinks, cordials and fruit juices should be consumed in a limited quantity because they are acidic in nature. Acidic food or drinks often soften the tooth material which leads to the dissolution of minerals into the tooth enamel, resulting in cavities (holes)

I have yellow teeth so is there any whitening gel or bleaching or any method for making teeth whiten at home.

I have yellow teeth so is there any whitening gel or bleaching or any method for making teeth whiten at home.
The simplest method of removing minor surface stains is polishing, or micro-abrasion if staining is more intrinsic. Provided that your discolouration is not due to inadequate enamel exposing the dentin, tooth whitening (bleaching) is often the most effective treatment for yellow stained teeth. Advance procedures can be done with laser. Use Snowdent tooth paste for whitening until then. Apply SNOWDENT paste on the teeth. Wait for 10 to 15 min .Then brush your teeth with the same paste. Applying it overnight for better results.

My tongue cannot taste anything. But I can feel the taste in my mouth but not my tongue. Please help doctors.
•An altered taste may result from dehydration, glossitis, a dry mouth, allergies, salivary glands infections, lack of zinc and vitamin B12, and polyps in the nose. •Others include breathing through the mouth, inflamed upper airways, and autoimmune diseases like Sjogren's syndrome and Bell's palsy. •Some injuries and traumas that cause a bitter taste include head, nerve, mouth and nose injuries, and biting your tongue. •Dental appliances such as braces, any surgery on your ear, nose, teeth or throat, and radiation therapy on your neck or head cause a bitter taste in mouth. •Gargle with water. Brush your teeth, tongue, roof of your mouth, and gums using toothpaste. Rinse your mouth with mouthwash. Drink liquids, chew sugar-free gum or mints, or suck on sour candies. Use plastic utensils if you have taste alteration when eating.

My friend is suffering from mouth odor, sometime suddenly blood come. what will he do? kindly give your expert opinion.
ask your friend to visit a dentist for professional cleaning of teeth. bad odour from mouth and bleeding gums are due to gum infection which develops due to deposition of plaque and calculus around teeth. professional cleaning will remove this layer and gradually problem will subside. also start warm saline rinses after treatment and follow oral hygiene habits properly.

You can exercise for healthier gums as well. Gently bite down so as to make sure that your teeth make a clinking sound when they meet. Repeat this 30 to 40 times continously. This exercise will stimulate the flow of blood and will keep your gums healthy.

Dengvaxia - first vaccine against dengue

Dengvaxia is a vaccine used to help protect adult or children against dengue disease caused by dengue virus serotypes 1, 2, 3 and 4. Dengvaxia is given to adults, adolescents and children 9 through 45 years of age living in endemic areas.

Full prescribing info - dengvaxia

Contents

Dengue tetravalent vaccine (live, attenuated).

Indications / uses

Dengvaxia is a vaccine used to help protect adult or children against dengue disease caused by dengue virus serotypes 1, 2, 3 and 4. Dengvaxia is given to adults, adolescents and children 9 through 45 years of age living in endemic areas.

Dosage / direction for use

The patient will receive 3 injections of 0.5 ml each at 6-month intervals.

The first injection will occur at the chosen or scheduled date; the second injection, 6 months after the first injection; and the third injection, 6 months after the second injection. Dengvaxia should be used according to the local vaccination schedule.

If the patient forgot an injection of dengvaxia: if the patient missed a scheduled injection, the physician will decide when to give the missed injection.

It is important that the patient follows the instructions of the physician, pharmacist or nurse regarding return visits for the follow-up injection. If the patient forgets or is not able to go back to the physician, pharmacist or nurse at the scheduled time, ask the physician, pharmacist or nurse for advice.

Administration: dengvaxia is given by the physician or nurse as an injection underneath the skin (subcutaneous route) in the upper arm.

Contraindications

Do not use dengvaxia if the patient is allergic (hypertensive) to the active substances or any of the other ingredients of dengvaxia listed in description (see description); has developed an allergic reaction after prior administration of dengvaxia. Signs of an allergic reaction may include an itchy rash, shortness of breath and swelling of the face and tongue; is suffering from a disease with mild to high fever or acute disease. In this case, the physician will postpone the administration of dengvaxia until the patient has recovered; has a weakened immune system, for example due to a genetic defect, hiv infection or therapies that affect the immune system (for example, high-dose corticosteroids or chemotherapy); is pregnant; is breastfeeding.

Use in pregnancy lactation: dengvaxia must not be given to pregnant or breastfeeding women.

If the patient is of child-bearing stage, the patient should take the necessary precautions to avoid pregnancy for 1 month following administration of dengvaxia; is pregnant or breastfeeding, the patient thinks may be pregnant or is planning to have a baby, ask the physician, pharmacist or nurse for advice before receiving dengvaxia.

Special precautions

Inform the physician, pharmacist or nurse before receiving dengvaxia if the patient is taking an immunosuppressive treatment (prednisone or equivalent to 20 mg or 2 mg/kg for 2 weeks or more). The physician will postpone administration of dengvaxia until 4 weeks after the treatment is discontinued; has experienced any health problems after prior administration of any vaccines. The physician will carefully consider the risks and benefits of vaccination.

As with all vaccines, dengvaxia may not protect 100% of persons who have been vaccinated. Vaccination with dengvaxia is not a substitute for protection against mosquito bites. The patient should take appropriate precautions to prevent mosquito bites, including the use of repellents, adequate clothing, and mosquito nets.

Fainting, sometimes accompanied by falling, can occur (mostly in adolescents) following, or even before, any injection with a needle. Therefore inform the physician, pharmacist or nurse if the patient fainted with a prior injection.

Adults above 45 years of age: adults above 45 years of age should not receive the vaccine.

Driving and using machines: no data are available on the effects of dengvaxia on the ability to drive or use machines.

Use in children: children less than 9 years of age should not receive the vaccine.

Side effects

Like all medicines, dengvaxia can cause side effects, although not all patients get them.

Serious allergic reactions: if any of these symptoms occur after leaving the place where the patient received an injection, consult a physician immediately: difficulty in breathing, blueness of the tongue or lips, a rash, swelling of the face or throat, low blood pressure causing dizziness or collapse.

When these signs and symptoms occur they usually develop quickly after the injection is given and while the patient is still in clinic or physician's surgery.

Serious allergic reactions are very rare (may affect up to 1 in 10, 000 people), after receiving any vaccine.

Other side effects: the following side effects were reported during clinical studies in children, adolescents and adults (from 9 to and including 60 years of age). Most of the reported side effects occurred within 3 days after the injection of the vaccine: very common (may affect more than 1 user in 10): headache, muscle pain (myalgia), generally feeling unwell (malaise), feeling of weakness (asthenia), injection site pain, fever.

Common (may affect up to 1 user in 10): injection site reactions: redness (erythema), bruising (hematoma), swelling, and itching (pruritus).

Uncommon (may affect up to 1 user in 100): infections of the upper respiratory tract, dizziness, sore throat (oropharyngeal pain), cough, runny nose (rhinorrhea), nausea, skin eruption (rash), neck pain, hardening of skin at the injection site (injection site induration).

Additional side effects in adults (from 18 to and including 60 years of age): uncommon (may affect up to 1 user in 100): swollen glands (lymphadenopathy), migraine, joint pain (arthralgia), flu-like symptoms (influenza-like illness).

Additional side effects in children and adolescents (from 9 to and including 17 years of age: uncommon (may affect up to 1 user in 100): itchy rash (urticaria).

Reporting of side effects or any suspected adverse event: if the patient experiences any side effects after vaccination, advised to seek immediate medical attention.

By reporting side effects, it can help provide more information on the safety of the vaccine.

Interactions

Using other medicines and dengvaxia: dengvaxia may not have an optimal effect if it used at the same time as medicines that suppress the immune system such as corticosteroids or chemotherapy.

Inform the physician, pharmacist or nurse if the patient is taking or has recently taken any other vaccines or any other medicines, including medicines obtained without a prescription.

Caution for usage

Before administering any biological, the person responsible for administration must take all precautions to prevent allergic or other reactions. As with all injectable vaccines, appropriate medical treatment and supervision must always be readily available in the event of an anaphylactic reaction following the administration of dengvaxia.

Epinephrine (1: 1000) and other appropriate agents used to control immediate allergic reactions must be available to treat unexpected events such as anaphylaxis.

Dengvaxia must not be mixed with other medicinal products in the same syringe.

Dengvaxia must not be administered by intravascular injection under any circumstances.

Syncope (fainting) can occur following, or even before, any vaccination as a psychogenic response to injection with a needle. Procedures should be in place to prevent injury from falling and to manage syncopal reactions.

Separate syringes and needles, separate injection sites and preferably separate limbs must be used if any other vaccine (s) or medicinal product (s) is/are concomitantly administered.

Dengvaxia is reconstituted by transferring all the solvent (0.4% sodium chloride solution) provided in the blue-labeled pre-filled syringe into the vial of freeze dried powder with a yellowish green flip off cap. The pre-filled syringe is fitted with a sterile needle for this transfer. The vial is then gently swirled. After complete dissolution, a 0.5 ml dose of reconstituted suspension is withdrawn into the same syringe. For injection, the syringe should be fitted with the new sterile needle.

The suspension should be visually inspected prior to administration. After reconstitution, dengvaxia is clear, colorless liquid with the possible presence of white to translucent particles (of endogenous nature).

After reconstitution with the solvent provided, dengvaxia must be used immediately.

Any unused dengvaxia or waste material should be disposed of, preferably by heat inactivation or incineration, in accordance with local regulations.

Do not throw away any medicines via wastewater or household waste. Ask a pharmacist on how to throw away medicines that no longer use. These measures will help to protect the environment.

Storage

Store in a refrigerator. Do not freeze. Keep the vaccine in the outer carton in order to protect it from light.

Description

After reconstitution, one dose (0.5 ml) contains 4.5-6.0 log10 ccid50* of each serotype of the cyd dengue virus** (1, 2, 3 and 4).

* ccid50: 50% cell culture infectious dose.

** produced in serum-free vero cells by recombinant dna technology.

The powder is a white, homogenous, freeze-dried powder with possible retraction at the base, and may form a ring-shaped cake.

The solvent (0.4% sodium chloride solution) is a clear, colorless liquid.

After reconstitution with the solvent provided, dengvaxia is a clear, colorless liquid with the possible presence of white to translucent particles.

Excipients/inactive ingredients: essential amino acids including l-phenylalanine, non-essential amino acids, l-arginine hydrochloride, sucrose, d-trehalose dihydrate, d-sorbitol, trometamol, urea, sodium chloride, water for injections.

Mechanism of action

Dengvaxia contains dengue virus serotypes 1, 2, 3 and 4 that have been weakened. Dengvaxia works by stimulating the body's natural defenses (immune system), which produces its own protection (antibodies) against the viruses that cause dengue disease.

Dengue is a viral infection transmitted to humans through the bite of an infected aedes mosquito. Dengue is not transmitted directly from person-to-person. Nevertheless the virus which replicates in an infected individual can be transmitted to other humans through mosquito bites for 4-5 days (maximum 12 days) after the first symptoms appear.

Dengue disease results in a wide range of symptoms including fever, headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, swollen glands or skin rash. Symptoms usually last for 2-7 days. Dengue disease can also be asymptomatic.

However, occasionally dengue can be severe and potentially lead to hospitalization and in rare cases to death. Severe dengue is characterized by high fever and any of the following symptoms: severe abdominal pain, persistent vomiting, rapid breathing, severe bleeding, bleeding in stomach, bleeding gums, fatigue, restlessness, coma, seizure and organ failure.

I'm suffering from mouth ulcer. Every month I suffered with this ulcer. I'm facing problems to eat food. Please give me solution.

MDS - Oral & Maxillofacial Surgery
Dentist, Chennai
If the mouth ulcer is causing a lot of pain, gently rub a small ice cube over the spot or rinse your mouth with ice-cold water. You could also chew on a clove bud (lavang) and direct the juice generated to the area where the ulcer is located. Clove buds are a great ingredient to cure sore throat too. To prevent the ulcerated area from getting infected, make it a point to rinse your mouth with a little salt water. Remember, this won’t make the ulcer disappear, but it can help reduce the pain. Honey is a natural humectant. It helps reduce scarring and hastens the process of new tissue growth. This, along with its anti-microbial effect ensures faster healing of the mouth ulcer. Chew a few leaves of tulsi along with some water about three to four times every day. This will help in getting rid of ulcers faster and also have a preventive action against their recurrence. Applying a little coconut oil directly onto the mouth ulcer or chewing some coconut (fresh or dry) helps reduce pain and inflammation and hence, ulcers heal faster. Mix some sugar to crushed khus-khus seeds and consume this mixture for instant relief from ulcers. You could apply a little ghee directly to the ulcerated area, or drink a glass of buttermilk two or three times every day. Mouth ulcers left untreated generally go away in a week or so; with these home remedies, you can expect faster relief. However, if you notice an ulcer in the mouth that is persistently present although it does not cause you any pain, do not neglect it or try to treat it with home remedies beyond a few days. Make it a point to see a doctor soon because often, a painless mouth ulcer is one of the earliest signs of oral cancer.

The yellow thing that you see is plaque accumulation, which also leads to bleeding gums and bad breath. You need to visit a dentist and get scaling (cleaning) done. In the mean time you can use a chlorhexidine mouthwash in a aqueous base twice a day.

This could b either due to sensitivity due to loss of enamel surface or due to decay of tooth. Tooth decay can b treated by filling of tooth or by rct n capping of the decay is deep. Sensitivity can b reduced by using desensitizing toothpaste such as senquelF or sensodyne toothpaste by rubbing some amount of toothpaste onto ur tooth surface n wait till 5 mins before rinsing it off. Get ur teeth evaluated by dentist to know the cause of ur problem n get treated accordingly. Regsrds.
