Dental Sealants in Da Nang

A thin protective coating applied to the biting surfaces of the back teeth to help prevent decay — a quick, preventive treatment for children and adults.

  • Children & adults
  • Preventive & quick
  • No drilling or anesthesia

Dental sealants are a thin protective coating applied to the biting surfaces of the back teeth. Molars have deep grooves that trap food and are difficult to clean thoroughly, which makes them a common place for decay to start. A sealant fills and covers these grooves so the surface is smoother and easier to keep clean.

At Vinmec Picasso, sealants are provided inside Vinmec Da Nang International Hospital as part of preventive care for both children and adults. They are often placed on a child’s new adult molars, but adults with deep grooves at higher risk of decay can benefit too. Whether sealants are worthwhile for a particular tooth is recommended after examination.

A simple, preventive step

Applying a sealant is quick and comfortable — there is no drilling and no need for numbing. The tooth is cleaned, prepared and coated, and the coating is set in place. Because it is so straightforward, it is especially well suited to children.

What sealants do and don’t do

Sealants protect the grooved biting surfaces where decay most often begins, but they do not protect the whole tooth, so regular brushing and cleaning between teeth are still important. Sealants are checked at routine visits and can be topped up if they wear over time. They are one useful part of prevention rather than a replacement for good home care.

Is it right for you?

Often recommended when:

  • Back teeth have deep grooves that trap food and are hard to clean
  • A child's new adult molars would benefit from added protection
  • You want a simple preventive measure to lower the risk of decay

May not be the right option when:

  • A tooth already has decay that needs a filling rather than a sealant
  • The biting surfaces are smooth and at low risk, so sealing adds little

Suitability is confirmed only after a clinical examination. Alternatives are discussed where they exist.

What the treatment involves

  1. Check & clean

    The teeth to be sealed are checked to confirm they are free of decay, then cleaned and dried.

  2. Preparing the surface

    The grooved biting surface is prepared so the sealant will bond well; no drilling or numbing is needed.

  3. Applying the sealant

    A thin protective coating is applied into the grooves and set, sealing the areas where decay most often starts.

  4. Check the bite

    The bite is checked and adjusted if needed so the sealed teeth feel comfortable.

Recovery & aftercare

  • You can eat and drink normally soon after the appointment.
  • Keep brushing and cleaning as usual, as sealants protect the grooves but not the whole tooth.
  • Sealants are checked at routine visits and can be topped up if they wear over time.

Common questions

Are sealants only for children?
No. Sealants are common for children as their adult molars come through, but adults with deep grooves at higher risk of decay can benefit too. Whether they are worthwhile is recommended after examination.
Does applying a sealant hurt?
No. Applying a sealant does not involve drilling or numbing. The tooth is simply cleaned, prepared and coated, so it is comfortable and usually quick, which makes it well suited to children.
Do sealants replace brushing?
No. Sealants protect the grooved biting surfaces where decay often starts, but the rest of the tooth still needs brushing and cleaning between teeth. They are one part of prevention, not a substitute for good home care.
