Dental Sealants

Highly effective in preventing decay on the biting surfaces of your chewing teeth, dental sealants are a simple procedure in which a tooth-colored acrylic “coating” is painted onto the surface of the tooth.

Dental sealants effectively “seals” the deep grooves, acting as a barrier and protecting enamel from plaque and acids.

Dental sealants protect the depressions and grooves of your teeth from food particles and plaque that brushing and flossing can’t reach.

Easy to apply, dental sealants take only a few minutes to seal each tooth. Sealants hold up well under the force of normal chewing and can last several years before a reapplication is needed.

Children and adults can benefit from dental sealants in the fight against tooth decay.

What to Expect During the Sealant Procedure

Applying dental sealants is quick, painless and does not require drilling or injections.

The process typically involves:

• Cleaning and drying the tooth
• Preparing the enamel surface
• Applying the tooth coloured sealant material
• Hardening the sealant with a special curing light

The entire procedure usually takes only a few minutes per tooth. Once applied, the sealant forms a smooth protective shield over the grooves of the tooth.

Who Should Get Dental Sealants?

As mentioned above, both children and adults can benefit from dental sealants. However, some people are better candidates than others. Here is a practical guide to help you understand whether dental sealants might be the right choice for you or your child.

Children and Teenagers

Children and teenagers are among the most common candidates for dental sealants, and for good reason. The permanent molars and premolars typically emerge between the ages of 6 and 14, and the deep grooves on these teeth are particularly vulnerable to decay during this period. Applying sealants as soon as these teeth come through gives them the best possible protection during the years when dietary habits and brushing technique are still being developed.

At Hornsby Family Dental Care, we often recommend sealants for children as a proactive step in preventing cavities before they have a chance to form. Sealants are a key part of children’s dental care, the procedure is quick, painless, and can save families from the cost and discomfort of fillings down the track.

Adults with Deep Grooves or Decay-Prone Teeth

Dental sealants are not just for children. Adults who have deep grooves or pits in their back teeth, but no existing decay or fillings in those areas, can also benefit significantly from sealants. If you have a history of cavities or find it difficult to keep the chewing surfaces of your back teeth clean despite good oral hygiene habits, sealants can provide an added layer of protection.

People at Higher Risk of Tooth Decay

Certain individuals are naturally more susceptible to tooth decay due to factors such as diet, saliva composition, or the anatomy of their teeth. If you or your child fall into any of the following categories, sealants may be particularly beneficial:

  • A history of frequent cavities or decay
  • Deep or narrow grooves in the back teeth that are difficult to clean effectively
  • A diet high in sugary or starchy foods and drinks
  • Limited access to fluoridated water
  • Difficulty maintaining a consistent brushing and flossing routine

When Sealants May Not Be Suitable

Dental sealants are a preventive treatment and are only appropriate for teeth that are free from decay and existing fillings. If a tooth already has a cavity or a restoration in place, a sealant cannot be applied. In these cases, the appropriate treatment is a filling or other restorative procedure.

Sealants are also not typically recommended for primary (baby) teeth unless a child is considered to be at particularly high risk of decay, in which case your dentist will advise on the most appropriate course of action.

Frequently Asked Questions

How long do dental sealants remain effective on teeth?
Dental sealants can last up to 10 years with proper care, but they often need to be checked regularly during dental visits. Over time, they can wear down and may require reapplication to maintain their effectiveness in preventing cavities. Ultimately, how long they last depends on the individual, their oral habits, and their unique dental circumstances.

What should you avoid after sealants?
After getting dental sealants, it is wise to avoid eating hard, sticky, or chewy foods for the first few days. These foods can dislodge or damage the sealants before they have had a chance to fully set. Maintaining good oral hygiene and avoiding habits like chewing ice or hard candy can help prolong the sealants’ effectiveness. The success of sealants varies depending on individual habits and specific circumstances.

What is the difference between a filling and a sealant?
A filling is used to restore a tooth that has already been damaged by decay. The dentist removes the decayed part of the tooth and fills the cavity with a material like amalgam or composite resin. A sealant, on the other hand, is a preventive measure applied to the chewing surfaces of healthy teeth, typically the back molars, to prevent cavities from forming in the first place. Sealants act as a protective barrier, whereas fillings repair existing damage. The choice between a filling and a sealant depends on the condition of the tooth and individual dental needs.

Are dental sealants safe?
Yes, dental sealants are considered safe and have been used in dentistry for decades. They are made from a tooth-coloured acrylic material and are applied directly to the surface of the tooth without any drilling or injections. The procedure is quick, painless, and suitable for both children and adults. If you have any specific concerns about sealant materials, our team is happy to discuss these with you during your appointment.

Do dental sealants require any special care?
Dental sealants do not require any special maintenance beyond a good oral hygiene routine. Continue brushing twice daily with fluoride toothpaste, flossing regularly, and attending your routine dental check-ups. During these visits, your dentist will check the condition of your sealants and recommend reapplication if any areas have worn down or chipped.

Can sealants be applied over early signs of decay?
Sealants are generally only applied to teeth that are free from existing decay and fillings. However, in some cases your dentist may apply a sealant over a very early, non-cavitated lesion to help prevent it from progressing further. This is a clinical decision made on a case-by-case basis. If decay is already present in the tooth, a filling or other restorative treatment will be recommended instead.

Does getting dental sealants hurt?
No. The application of dental sealants is a completely painless procedure that does not involve any drilling or anaesthetic injections. The tooth is simply cleaned, prepared, and coated with the sealant material, which is then hardened using a special curing light. Most patients, including young children, find the process straightforward and comfortable.

How much do dental sealants cost?
The cost of dental sealants can vary depending on the number of teeth being treated and your individual circumstances. Some private health insurance policies with extras cover may include sealants under preventive dental care. We recommend checking with your health fund prior to your appointment. Our team at Hornsby Family Dental Care is happy to provide a clear cost estimate and discuss any available payment options during your consultation.
