Frequently Asked Questions

Q: What are fissure sealants?

Fissure sealants are plastic tooth coloured coatings, which are applied onto the chewing surface of the back teeth to help prevent tooth decay.

Q: Why fissure sealants?

A: Fissure sealants are commonly used to prevent tooth decay, caused by sugar from food or drink, that collects in the fissures or grooves on your back teeth, which toothbrushes cannot reach. When the fissure sealants are applied onto the teeth, it covers the grooves, hence shielding them from food particles or plague.

Q: How are fissure sealants done?

A: Depending on the sealant material, the sealants are typically applied on dry teeth, and then hardened by dental curing light. Once this painless procedure is done, the sealants can last for many years.

Q: What is periodontal disease?

Periodontal disease is a bacterial infection or inflammation of tissues that destroys the structures that hold your teeth in place. It is also known as “gum disease”. There are basically two types of periodontal disease:

  • Gingivitis
    This is the basic inflammation of the gums. Many people with poor oral hygiene will have gingivitis at some stage. However, if gingivitis is not treated, it will eventually lead to periodontitis.
  • Periodontitis
    Periodontitis is a major cause of tooth loss. This is the destructive stage of infection that can destroy all the periodontal tissues including the gums, bone, and other periodontal tissues, which cause loose teeth, infected gums, bad breath and foul taste.

Q: What causes periodontal disease?

A: Periodontal disease is caused by the reaction of bacteria in the plague that collects on the teeth over time. Plaque that continues to grow without being treated becomes calcified, and turns into calculus or “tartar,” which causes inflammation of the gums.

Q: What is the treatment for periodontal disease?

A. Gingivitis – There are a number of ways to prevent and cure gingivitis. The simplest way to prevent it is by homecare method, which includes brushing and flossing to remove plague that collects on the teeth. If the condition is already severe, patients will need professional cleaning by a hygienist or dentist.


– Treatment for periodontitis is more serious than for gingivitis. It requires a combination of both home care and professional treatment to prevent and cure the disease. Professional treatment includes numerous visits for scaling and root planning, and possibly antibacterial medication that can be taken orally or applied to the gums. With chronic periodontitis, gum surgery is necessary to remove the calculus, underneath the gum line.

Q: Will periodontal disease occur again after treatment?

A: Periodontal disease can occur again if the patient’s health in general is poor, and the regular cleaning is not well maintained after the professional cleaning is done. If the disease has spread into the roots, it is rather difficult to remove the calculus completely.

Q: How can I tell if I have bad breath or halitosis?

A: Unfortunately, we are not always aware of our bad breath. A dry mouth or bad taste is a good indication that you may have halitosis. Also, if you smoke and often consume strong aroma foods like curry, garlic and onions, your chances of having bad breath is excessive. The best way to tell is to rub your finger across your teeth, and then smell it or check with your partner or close friends.

Q: What are the causes of bad breath?

A: Below are most common causes of bad breath

  • Poor oral hygiene at home
  • Gum disease like gingivitis or periodontitis
  • Consumed strongly flavoured foods
  • Cigarettes
  • Constant dry mouth or xerostomia
  • Other medical or oral problems

Q: How do I cure bad breath and have fresh breath?


  • Maintaining a good oral hygiene at home is by brushing and flossing your teeth twice a day.
  • Remember to clean your tongue too.
  • If you are wearing any dentures, make sure they are removed at night, and clean them before wearing it again in the morning.
  • Visiting your dentist at least twice a year to check on your overall oral hygiene, and cleaning the teeth professionally to remove plaque that you can’t remove with normal brushing or flossing.

Q: What are the different types of teeth whitening options?


  • Professionally Dispensed Take-Home Whitening Kits
    You can purchase these whitening kits from your dentist. This method takes a longer time to take effect, but the results are similar to when opting for in-office teeth whitening. Gel is placed on teeth trays and to be worn like dentures. The gel is less active, and the teeth trays are usually worn over a few days or weeks, depending on the products and condition of your teeth. This is best if you already have sensitive teeth.
  • In-office teeth whitening
    In-office teeth whitening is conducted at the dentist’s office, by applying high-concentrated gel on the teeth to produce a prominent colour change in teeth. This method brings about the best result in the shortest time.

Q: How often should I visit the dentist?

A: Patients are recommended to visit the dentist at least twice a year. With regular dental visit and examination, you can detect early signs of any oral disease that you may not usually see.

Q: How often should I brush and floss my teeth?

A: You should brush your teeth at least twice a day, once in the morning after breakfast and once at night before heading to bed. You should also floss once a day. We recommend this to be done at night to remove all food particles that may be collected during the day.
