A commonplace for bacteria to attack is your tooth’s chewing surface. This mainly happens because the natural grooves of your teeth are difficult to clean. Luckily, this is where sealants come in handy. Specifically, sealants are applied to protect your teeth by filling in tiny areas of your teeth’ exterior. Moreover, sealants guard your teeth against erosion caused by bacteria. Though adults also benefit from dental sealants in San Diego and Temecula, they are most useful for children ages 5 to 12. Furthermore, dental sealants can last for up to two to four years. You can always replace them to prevent cavities and other potential dental issues.
