Teeth can be whitened by a procedure called Teeth Bleaching which is generally quite a safe procedure but has to be done under the supervision of your dentist.

Here is home remedy for brighter teeth--- mix several teaspoons of baking soda with enough fresh lemon juice (or water) to make a paste. Wipe your teeth and any extra saliva off of them with a paper towel. Put a good amount of paste onto your toothbrush and apply. Leave the paste on for 1 minute, then rinse, so as to avoid the acid effecting enamel. If you are using just water you can leave it on for up to 3 minutes. For faster result you can go for teeth bleaching from dentist.

There are scratches in my teeth and till date I have never gone for cleaning of my teeth. I would like to clean my teeth and remove scratches from the teeth.

Well you need to go for scaling (tooth cleaning)& polishing of teeth. Some dentist only perform scaling & not polishing so it is very important that you ask them to perform polishing after scaling. Minor scratches as you said will fade away.

Hello doctor, I consulted a doctor a month ago and he prescribed me to take omega 3 and vitamin capsules. I followed the same. Today I met a friend who is a Amway representative and he showed me a experiment in which he put the cut tablet on thermocol and it started to melt. So is it safe to continue or is that common experiment? Thank you doctor.

It is safe to continue if you can see benefits. Do not get misguided by one odd experiment. All drugs go through stringent quality checks before floating in the markets and getting prescribed.

Bad breath can be due to various reasons other than dental problems too. If you have any issues like constipation or acidity or sinusitis etc, you need to get the root cause of the problem treated. In the meanwhile you can use any over the counter mouthwash and maintain a good oral hygiene which will reduce the bad smell to some extent. Also, you need to get your teeth examined by a dentist to check for any accumulated tartar in between your teeth which can lead to the problem, this can be easily overcome by a thorough dental cleaning.

What can you do for your cold or cough symptoms? besides drinking plenty of fluids and getting plenty of rest, you may want to take medicines. There are lots of different cold and cough medicines, and they do different things. Nasal decongestants - unclog a stuffy nose...i.e ................ nasal dop/spray.....nasivion Cough suppressants - quiet a cough...................................... syp. Brozedax Expectorants - loosen mucus so you can cough it up.............syp...zeet expectorant Antihistamines - stop runny noses and sneezing.....................tab/syp....levocetirizine Pain relievers - ease fever, headaches, and minor aches and pains.......tab..flucold plus . Here are some other things to keep in mind about cold and cough medicines. Read labels, because many cold and cough medicines contain the same active ingredients. Taking too much of certain pain relievers can lead to serious injury. Do not give cough medicines to children under four, and don't give aspirin to children.

Hello Lybrate-user, sensitivity is sharp, shooting type of sensation in teeth on contact of extremely cold or hot food which usually lasts for a few seconds and disappears completely after that and re-occurs again on such stimulus. Treatment plan for sensitive teeth goes as follows: 1. You can use any commercially available desensitizing toothpastes such as colgate sensitive /sensodyne /Sensodent KF / Sensoform R/ Shy NM/ Vantej /Senquel F /Shy XT /Pepsodent pro sensitive (many more are available in market) as first line of treatment. If it reduces your sensitivity substantially you can continue brushing with toothpaste in long run to avoid further sensitivity. 2. If you don't get any relief from desensitizing toothpastes it indicates a more severe problem which will need further treatment like layering/coating the damaged tooth surface OR filling of the tooth if there is big cavity OR root canal treatment in extreme cases. Getting proper treatment leads to permanent relief in sensitivity problem. And you can eat and drink cold food items without getting jerks while eating or drinking. Regards

Nothing to worry about. At the age of 6 years don't forget to get an xray done. It will confirm the eruption of the permanent teeth.

All About Laser Dentistry - Methods and Results

A very interesting thing, that most people would have noticed during their visit to the clinic is the white light that is used on the teeth. This is laser light, which is used extensively over the last couple of decades in dentistry for a variety of treatments. The following are some procedures where laser is commonly used.

  1. Whitening teeth: In-office bleaching is done by applying the whitening agent on the tooth and activating it by laser light. This instant result is whiter teeth and a brighter smile.

  2. Caries: In some cases, laser light is used to remove the decayed portion of the tooth and shape the surrounding healthy tooth to receive the restorative material.

  3. Restorations: When composite resins are used to fill the space left by tooth decay, the decayed portion is removed and the enamel etched to improve adhesion. The composite material is then filled in the tooth space to achieve the desired shape and then light-cured.

  4. Veneers: Where a thin layer of the existing tooth is removed to provide a whiter tooth, then laser light is used. These chemicals are inactive and only become activated when exposed to laser light. In cases of both restorations and veneers, one big advantage is it gives sufficient working time for the dentist to shape the material to the desired form and then activate it.

  5. Gingivitis: Laser is also used in gum diseases where bacteria are removed and the gums are reshaped. Using laser on the root surfaces ensures better removal of the hardened calculus and promotes gum reattachment of the gums to the tooth surfaces.

  6. Root canal therapy: In the root spaces, if there was an infection, laser light can help remove the bacteria before filling up the root canal with gutta percha.

  7. Soft tissue biopsy or lesion removal: Biopsies of the lips, gums, and tongue can be done using laser light. If the lesions are too small and require removal, it can be done by laser, thereby avoiding the need for surgery

Results: In all the above procedures, the laser is more effective than the conventional method that it is replacing. Some advantages include:

  1. Less painful

  2. Anesthesia not required

  3. Avoids tooth drilling in some cases of very minor decay, so patient is at ease

  4. Reduces bleeding and swelling when dealing with soft tissues

  5. Reduces the amount of tooth removal during cavity preparation

Not all situations can be managed with a laser treatment though and conventional biopsies and drills will be required in some cases. As with all other dental situations, a detailed discussion with the dentist on the pros and cons and the patient condition will help make an informed decision.

I am 30 year male, I had H1S1 (Herpes Simplex) in Oct 2015. It started with gum swelling right behind my front tooth followed by fever and finally entire mouth got badly infected with 4 prominent sores on lips. Initially doctor thought it is local allergy but when it worsened he prescribed Ocuvir 800 (thrice a day). Slowly things improved, sores and everything went away except the swelling behind the gums from where everything started. It reduced but didn't go away completely. I had read on internet that the H1S1 virus would never go and will come back again and again but with lower intensity. I asked my doc will it come back he said it won't and assured me it is nothing to worry about. He also checked my recent blood report and said I am perfectly normal nothing to worry about. BUT after one and half year I am concerned about following - 1. After first instance in Oct 15, it has returned at least for 5-6 times. Very mild in nature compared to first time. Now it starts from one of the four sores I had on lips. I always take Ocuvir 400 myself, as I see the symptoms and it gradually goes away. Is that right? 2. The swelling behind gums is there since Oct 15. It has never gone. I feel it softens or increases. 3. Should I visit a dentist and get mouth cleaned? Or any other suggestion. 4. Is there a way I can get rid of this forever? Open to nature/homeopathy, Ayurveda as well. Please Suggest! Thanks in advance.

Disease recurs with low intensity. You can do this thing. Take proper balanced vegetarian diet. Take 8 to 10 glasses of water daily to detoxify body. Take fruits and vegetables in daily diet. Avoid non veg and eggs always. Take milk and milk products in diet. This will improve your immunity.

You may need cleaning, root canal treatment & capping. Rinse frequently with mouth wash. Advise c. Amox 500mg 1-1-1, thrice, t. Metrogyl 400mg 1-1-1, thrice, t. Imol 1-1-1, thrice (contraindicated in conditions with gastric ulcer, asthma, wheezing, and allergy), and c. Becosules 1-0-0 once, all for 3 days only.

All individuals requires scaling (cleaning) to be done atleast once in 6 months to maintain our oral hygiene clean. Our toothbrush is not much finely designed to clean all the plaque and calculi in the interdental areas of the teeth, which is the area where most of the calculus accumulate much and has to be removed regularly using scalers by the dentist. For some patients tooth will will appear to be firm only because of the calculus holding it, not the bone. In such cases after removing those calculus by scaling results in loosening of the tooth, but scaling is actually good since it removes the calculus and maintains your oral hygiene safe.

Hi. I have throat pain from last 3 days. I am not able to swallow any thing. please advice me what to do.
If tooth pain is so severe then you need to go for root canal treatment for that tooth. If swallowing is difficult then it can also be due to tonsillitis. All that can be checked once you consult a dentist. Hope you get well soon.

Avoid sticky sweets, such as toffees, soft candies and pastries. These types of foods stick to your teeth and feed decay-causing bacteria. When you do eat sweets, eat them after a meal. When candies are eaten alone, they are more likely to remain stuck between your teeth.
