What you must know before you get root canal treatment

Root canal treatment also known as endodontics is performed to treat and heal an infected or badly damaged tooth rather than removing it. When your teeth start decaying, you do not feel any pain for a very long time. However, gradually the darkening of your tooth color may become prominent which could mean that the tooth nerve is dying or has died. That's the time you will need root canal treatment which involves cleaning of the canals inside the roots of your tooth.

Why you may need the root canal treatment

Teeth consist of a soft core known as dental pulp. This pulp goes beyond the crown and the noticeable part of your tooth to the root tip inside your jawbone. The pulp contains blood vessels, nerves, and connective tissue. So when your tooth is damaged or has a severe cavity, bacteria can easily make their way through the pulp. Symptoms and signs of a sore tooth include a hole in your tooth, a swelling around the regions of your face and neck, gum swelling, tooth pain or a toothache and temperature sensitivity. If it is left untreated, the decaying material and bacteria can cause a tooth abscess or severe infection, resulting in a bone loss, pulp death and even loss of the tooth itself. The root canal treatment is the best way to save the damaged teeth and escaping the painful process of extraction.

What does the treatment involve?

The purpose of the treatment is to free your root canal from every possible infection. The root is then cleaned and filled to avoid any further infection.

Root canal treatment is a skilled procedure which is time-consuming and usually requires from 2-3 visits to your dentist.

In the initial stage, the infected pulp is isolated to drain out abscesses (if any), followed by the cleaning of your root canal which is then prepared for a temporary filling.

Your tooth is then left to settle down.

In the next visit, your tooth is checked to see whether it’s free from all forms of infection so that it can be permanently filled.

I have been suffering for last 15 days with a tongue ulcer and treating with homeopathy medicine. Doctor told nothing to be worried. I do smoke. After 15 days also it is not come down. Please guide me.

An ulcer lasting that long may be misdiagnosed, insist on getting a tissue biopsy done. Meanwhile keep the mouth clean. Swish & spit with warm salt-water after meals, till suggested otherwise.

1)Replacement of amalgam restorations 2)Withdrawal of the drug 3)Oral lichen lesions in chronic in graft versus host disease are usually managed with local corticosteroids or other drugs such as tacrolimus. 4)As in OLP the question arises whether one or all types of oral lichenoid lesions are to be considered a potentially malignant disorder In the absence of known etiological factors, the taking of a biopsy should be considered, particularly in case of a non-reticular lesion, in order to exclude the possibility of epithelial dysplasia or even carcinoma in situ or invasive squamous cell carcinoma. The term “lichenoid dysplasia” is confusing and, therefore, should be avoided.

When plaque and tartar accumulate in the teeth, they give rise to gum diseases. But if taken care of at the right time, they can reversed at the initial stage itself. By getting the plaque and tartar removed from the teeth, you can easily get rid off them.

There is an ulcer in my mouth on both sides. I'm worrying that it can be cancer. There is no pain, however. Kindly help.

You can't say that this is cancer by just seeing. You hav to go some conformation test. I will suggest consult your dentist.

Attrition of teeth is a natural process with time and the surface gets attrition slowly and become sensitive. And can cause sensitivity in teeth and mild headache due to temporo mandibular joint pain. Please visit a prosthodontist he will examine her and advise you accordingly.

Hello I am getting bad smell from teeth, it also become yellowish how can I solve it by home made treatment.

•Eat a healthy, balanced diet and avoid eating strongly flavoured or spicy food. •Cut down on sugary food and drink, as it can increase the amount of bacteria in your mouth. •Reduce your alcohol consumption. •Stop smoking. •Cut down on coffee. •Drink plenty of water to help prevent your mouth becoming dry. •Chew sugar-free gum after eating, to stimulate the flow of saliva. This will help clean away any remaining food particles. •Don't use toothpaste to clean your dentures, as it can scratch the surface and cause stains. •Clean your dentures thoroughly using soap and lukewarm water, denture cream or a denture-cleaning tablet. •Use a separate toothbrush to clean your dentures. •Make sure you visit your dentist for regular check-ups. Having regular dental check-ups will ensure that any plaque is removed from your teeth, particularly in areas that are difficult to reach. •Your dentist can recommend the best way to clean your teeth and gums, and point out areas you might be missing. They can also identify any signs of gum disease and ensure early treatment. •Gastritis, lung & sinus infection may also be the cause of bad smell in the mouth. 90% of bad breath is due to a dirty tongue. •If your bad breath is caused by a gastrointestinal problem, such as an H. Pylori infection or gastro-oesophageal reflux disease (GORD), you may be referred to a gastroenterologist. •Persistent bad breath or a bad taste in the mouth may be a warning sign of gum (periodontal) disease. Gum disease is caused by the buildup of plaque on teeth. •You may need deep cleaning & fill tooth cavities with artificial enamel filling. Rinse your mouth thoroughly with a mouth wash until then. Advance procedures can be done with laser too. You may consult me in person.

I have put teeth braces yesterday. I can t eat properly. Which foods I should avoid.

Dentist, Hyderabad
Hard, and sticky food should be avoided, and try to take juices and very soft food that you do not need to chew, and swallow it readily, but that also should be nutritious.

My age is 16 yrs. My orthodontist has recommended braces to be put on to my teeth and said that two teeth need to removed. How tooth extraction is done? Will it be very painful to remove my two teeth? I would be waiting for reply.

Dentist, Vadodara
No need to worry about tooth extraction. Doctor will give you local anasthesia and then remove your tooth. It is a completely painless procedure. You need not worry at all.

My teeth is in light yellow colour to whiting teeth what is the home made remedy for it.

Dental Clinic
Dentist, Gurgaon
To avoid yellowing of teeth at home you can brush your teeth twice a day and use a mouthwash at night. Even then if you do not see a change then visit a periodontist for a professional cleaning of teeth. And if the yellowness is due to some internal stains then you can go for bleaching.

I have yellow teeth and my ponies less tha 7 inch I want to long penis more tha 7 inch so please help me.

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.

Try to save a knocked out tooth. If possible, hold the tooth back in place while you seek immediate dental advice. If this is not possible, wrap the tooth in plastic or place it in milk and seek dental advice immediately.

Nicles you are having cavities . having blood in mouth in morning shows poor oral hygiene . The best way to get rid cavities is filling of cavities regular rinse with Mouthwashes (listerine )after meals . you have to visit dental surgeon ,for filling .and ensure your teeth stay healthy.

You can go, age is not the factor.Your bone support and the condition of the gum is what is going to matter.If you have a good support of the teeth teeth treatment result will be better. Price and treatment time will depend on the condition you have.
