Our Services

Preventive Dentistry

In our clinic, we will choose the preventive methods of dental cavity and periodontal disease according to the individual oral condition. These include the removal of cariogenic and periodontopathic bacteria, the intake of xylitol, topical application of fluoride, rinsing of fluoride and so on.

Healthy teeth and gums are the foundation of oral health. A periodic tooth cleaning is important for several reasons. It lets us remove the tartar and plaque that build up around your teeth, helping prevent periodontal disease. Also, when you come into our clinic on a regular basis, we can monitor the health of your teeth and gums and look for any signs of changes or problems.


Cariogenic bacteria will initially attach baby’s mouth via mainly the mother’s saliva when baby’s teeth come out. Therefore, parents and their families should finish the treatment of dental cavities. To prevent infant dental cavities, the child should refrain from eating sweets until they are at least 3 years old.

Orthodontics (Invisalign)

Invisalign takes a modern approach to straightening teeth, using a custom-made series of aligners created for just you. These aligner trays are made of smooth, comfortable and virtually invisible plastic that you wear over your teeth. Wearing the aligners will gradually and gently shift your teeth into place, based on the exact movements we plan out for you. There are no metal brackets to attach and no wires to tighten. You just pop in a new set of aligners approximately every two weeks, until your treatment is complete. You’ll achieve a great smile with little interference in your daily life.

Cosmetic Dentistry

The first thing most people notice about you is your smile. Advances in cosmetic dental care have made it possible for a dentist with the right training, qualifications and expertise to completely redesign your smile.
