Dental Sealants by Local Dentist

Protecting Teeth with Preventive Care

Why Dental Sealants Matter

Even with daily brushing and flossing, food particles and plaque and bacteria can collect in the deep grooves of molar teeth and premolar teeth, increasing the risk of cavities. Dental sealants provide an effective cavity prevention solution by covering these vulnerable areas with a thin composite resin coating that helps block decay-causing bacteria and protects the dental enamel.


At Eddie Kao DDS, we provide dental sealants in Tustin, dental sealants in West Covina, and preventive dental sealants for children, teens, and adults who are more susceptible to cavities or have deep chewing surfaces. This quick, comfortable treatment supports long-term tooth decay prevention and helps keep your smile healthy for years to come.

The Dental Sealant Process

Dental sealants are one of the simplest and most effective preventive dentistry treatments we offer. The procedure is completed in a single visit and includes:


  • Cleaning and drying – The tooth surface is cleaned and prepared for bonding.
  • Application – A durable composite resin coating is carefully applied to the chewing surface.
  • Curing – The sealant is hardened using a special curing light, forming a durable, protective layer.


Once applied, pit and fissure sealants help shield the grooves of your back teeth from plaque and bacteria, significantly reducing the risk of cavities in areas that are difficult to clean.

Lasting Protection for Healthy Smiles

Benefits of Dental Sealants

Dental sealants are a simple, effective way to protect your smile and reduce the risk of future cavities. They:


  • Help prevent cavities and tooth decay.
  • Protect dental enamel from harmful acids and bacteria.
  • Are virtually invisible and comfortable to wear.
  • Last for several years with proper oral hygiene and routine dental care.


Our team at Eddie Kao DDS monitors your sealants at every checkup to ensure they stay strong and effective, helping you maintain a healthy, cavity-free smile.
