How Dental Sealants Are put On

Application of Dental Sealants

The process of applying dental sealants is straightforward and typically performed by a dentist or dental hygienist during a routine dental visit. Here’s how dental sealants are put on:

1. Preparation:

Before applying sealants, the teeth are thoroughly cleaned and dried to ensure optimal bonding of the sealant material. Any debris or plaque on the chewing surfaces of the teeth is removed using a dental scaler or polishing instrument.

2. Isolation:

To keep the teeth dry during the sealant application process, cotton rolls or a special dental dam may be used to isolate the teeth from saliva and moisture in the mouth. This helps ensure the sealant material adheres properly to the tooth enamel.

3. Etching:

A mild acidic solution or dental etchant is applied to the chewing surfaces of the teeth to create a roughened surface for better adhesion of the sealant material. The etchant is left on the teeth for a short period, usually around 15 to 30 seconds, and then rinsed off thoroughly.

4. Drying:

After etching, the teeth are dried completely using an air syringe or absorbent materials. Ensuring the teeth are dry is essential for the sealant material to bond effectively to the enamel and provide long-lasting protection against decay.

5. Application of Sealant:

Once the teeth are dry, the sealant material is applied to the chewing surfaces of the teeth using a small brush or applicator. The sealant is carefully painted onto the pits and fissures of the teeth, covering the entire surface area where decay is most likely to occur.

6. Curing:

To harden the sealant material and create a durable protective barrier, a curing light is used to expose the sealant to a special wavelength of light. The light activates the chemical components in the sealant, causing it to harden within seconds.

7. Evaluation and Adjustment:

After the sealant material has hardened, the dentist or dental hygienist will evaluate the sealants to ensure they have been applied correctly and cover the entire chewing surface of the teeth. Any excess sealant may be trimmed or adjusted as needed.

8. Final Polishing:

Once the sealants have been properly applied and evaluated, the teeth may be polished to remove any rough edges or excess sealant material, leaving the teeth smooth and comfortable.

Other Tips To Help Prevent Tooth Decay

In addition to dental sealants and basic oral hygiene practices, there are several other strategies you can implement to further reduce the risk of tooth decay and maintain excellent dental health. Here are some additional tips:

1. Rinse with Fluoride Mouthwash:

Incorporate a fluoride mouthwash into your daily oral hygiene routine. Rinsing with fluoride mouthwash helps strengthen tooth enamel, remineralize weakened areas, and reduce the risk of cavities.

2. Limit Acidic Foods and Beverages:

Acidic foods and drinks, such as citrus fruits, vinegar-based dressings, and carbonated beverages, can erode tooth enamel and increase susceptibility to decay. Limit your consumption of acidic items and rinse your mouth with water afterward to minimize acid exposure.

3. Chew Sugar-Free Xylitol Gum:

Chewing sugar-free gum sweetened with xylitol stimulates saliva production, which helps neutralize acids in the mouth and rinse away food particles. Xylitol has also been shown to inhibit the growth of cavity-causing bacteria.

4. Use a Tongue Scraper:

In addition to brushing and flossing, use a tongue scraper to clean the surface of your tongue. Bacteria and food debris can accumulate on the tongue, contributing to bad breath and oral bacteria that may lead to decay.

5. Avoid Tobacco Products:

Smoking and using tobacco products not only stains teeth and contributes to gum disease but also increases the risk of tooth decay and oral cancer. Quitting smoking and avoiding tobacco altogether can significantly improve oral health.

6. Drink Tap Water:

Opt for tap water over bottled water whenever possible, as many municipal water supplies contain fluoride. Drinking fluoridated water helps protect teeth from decay and strengthens enamel, contributing to overall oral health.

7. Consider Dental Treatments:

Discuss preventive dental treatments with your dentist, such as fluoride treatments or dental varnishes. These treatments can provide additional protection against decay, particularly for individuals at higher risk.
