1. What are the types of teeth?

There are two types of teeth: the primary, often called 'baby' or 'milk' teeth, and the permanent teeth. There are 20 primary and 32 permanent teeth. In some persons, one or more of these teeth may be absent, or there may be one or more extra, or supernumerary, teeth.

2. What is a healthy tooth?

A healthy tooth is strong and clean with solid bones and sound gums. It is free from cavities and decay.

3. How does tooth decay start?

When food particles are left on the teeth, especially sugary food, bacteria turn them into acid which eats way into the Enamel*, then into the Dentine* and finally into the Pulp*. This can be very painful. When the decay reaches the roots, the teeth may have to be pulled out.

Top


4. What is gum disease?

Bacteria in Plaque can release substance that irritate and inflame gum tissues. This condition is called Gingivitis. When Plaque is not removed, it hardens around the gum line and forms Tartar. The infection then spreads to the bone supporting the tooth and eventually, the tooth may fall out. This is called Periodontal disease or Pyorrhea. (A Periodontist like Dr. Shalini Agarwal is a qualified dentist to treat such cases of gum disease). Gum diseases may also take the form of a gum boil which results from infected pulp. As pus collects, it works its way through the end of the root and into the jaw bone and pushes out the gum to resemble a boil.

5. How can tooth decay and gum disease be prevented?

Follow the 5 golden rules:

a) Eat foods enriched with vitamins and minerals.

b) Avoid eating sweet or sticky foods between meals.

C) Brush your teeth after every meal.

d) Use trusted dental aids recommended by dentists.

e) Visit the dentists once every six months to ensure good dental health.

6. When should you consult your dentist?

At the appearance of any of the following symptoms, consult your dentist immediately: toothache; bleeding gums during brushing; persistent unpleasant breath; cavities; painful sensations; teeth growing out of order; swollen, loose or flabby gums and loose teeth.

Top


7. Is professional cleaning of the teeth necessary?

Yes, because even the most careful and conscientious can leave some Plaque and Tartar deposits. Therefore, it is usually necessary to have your dentist give your teeth a professional cleaning every 6 months. Professional cleaning or scaling improves periodontal health.

Top


8. What can happen if missing teeth are not replaced by artificial teeth?

If missing are not replaced by artificial teeth, the adjacent teeth will, over a period of time, lean into the empty space. Food is likely to accumulate between the remaining teeth, providing a breeding ground for decay-causing bacteria. Irregular spacing also makes cleaning of teeth difficult and leads to formation of Tartar. Further, the pressure caused by chewing is not properly distributed among the remaining teeth. This uneven pressure may contribute to the destruction of gums and bone. So removable or permanent artificial teeth that replace the missing teeth will help you maintain your dental health.

Top


9. Should you use a mouthwash?

You may use a mouthwash if you want to freshen your breath temporarily. But do not expect it to remove Plaque and prevent tooth decay and gum disease. Bad breath may indicate some other bodily disorders. Do not mask these signs of trouble by using mouthwash.

Top


10. What harm can irregular or malformed permanent teeth do?

Irregular or malformed permanent teeth can be hindrance to brushing which may lead to formation of Tartar on the teeth, and finally, to tooth decay and gum disease. They also interfere with chewing, good speech habits and appearance. For advice, consult your dentist. He will recommend the necessary orthodontic treatment or a minor surgery.

Top


11. What is the proper age at which to begin correcting irregular teeth?

An age of 8 years is ideal for a child to correct his irregular teeth. The  Dentist after diagnosing will decide when the treatment is necessary.

Top


12. Is thumbsucking harmful to child's dental health?

Thumbsucking during the first year or two of a child's life need not cause any concern. Any irregularities in the position of teeth that is directly due to sucking habits will probably correct itself if it corrects before the age of 5. After that however, thumb or finger sucking may affect the position of the incoming teeth and shape of the jaws. So, the child should be discouraged from sucking the thumbs or fingers.

Top


13. What is the relation between nutrition and dental health?

Calcium and phosphorous are necessary for hardening of the tooth structures during the years of the teeth are being formed. A balanced diet throughout life is adequate for dental health.

Top


14. Should you give your child calcium tablets while teeth are forming?

According to most authorities, the best source of calcium is the daily diet. If a child eats a balanced diet and drinks an adequate amount of milk, he will obtain all the calcium and phosphorous he needs. Ask your dentist or doctor for any dietary supplement if necessary.

15. What should be done if you accidentally break or crack a tooth?

You should visit your dentist immediately. The dentist will probably take and x-ray examination and then place medicated cement over the sensitive part of the fractured tooth. Or, he may smoothen the rough edges of the break. If it is a serious fracture, he may place a band or a crown over the tooth to protect it. If the tooth is knocked out, try and rinse it in water and try and place it in the socket from where it has detached, in case that does not fit well, wrap it in a wet cloth or place it in milk. Then visit the dentist as early as possible. In many cases it is possible to re-attach the tooth to the jaw so that it functions normally.

16. At what age should you take your child to the dentist for first time?

Your child's first visit to the dentist should be when he is between 2 and 3 years of age. However, if a child younger than 2 has a cavity, or his teeth are injured in an accident, he should of course, be taken to a dentist for examination and the necessary treatment.

Top


17. Should X-ray pictures be taken of children's teeth?

Top


18. Why does tooth sensitivity occur?

a) Wrong/aggressive brushing can wear down the enamel causing sensitivity.

b) Receding gums can expose the roots of the teeth, causing pain.

c) After layers of Tartar are scrapped off by the dentist, teeth could become  sensitive to cold air.

Top


19. What causes tooth discoloration?

Teeth can discolor due to variety of reasons:

a) The commonest discoloration is due to smoking or tobacco.

b) Food and beverages such as tea, coffee, colas and red wine can be the culprit.

25. What is a Porcelain Laminate Veneer?

26. How is a Crown different from a Veneer?

A Crown, often called a "cap" covers the entire tooth, unlike a Veneer which covers only the front surface of a tooth. A Crown requires more shaping of a tooth structure and is often used to strengthen a weak or broken tooth. Crowns are extremely durable, aesthetic and are commonly used in the front and the back of the mouth.

27. When is a Root Canal Treatment needed?

A Root Canal Treatment is needed when a tooth's nerve and associated blood vessels are irreversibly damaged either by trauma to the tooth or because of the tooth cavity. This results in infection that may lead to an abscess at the base of the tooth.
