The chewing surfaces of your back teeth (molars) have deep, narrow grooves (fissures) where toothbrush bristles cannot reach. Food and bacteria easily get trapped here, starting a cavity. A sealant is a safe, painless, liquid resin that flows into these deep grooves and hardens under a special light, creating a smooth, flat shield that physically blocks bacteria from entering the tooth.

An MDS Public Health specialist utilizes evidence-based behavioral therapies (the 5A's model) and can coordinate pharmacological aids (like nicotine replacement therapy) to guide you safely through the withdrawal process.
