1 BPA does indeed form in the mouth after some dental sealants and fillings are applied. BPA can be found in the saliva three hours after dental work is completed. It's not at all clear whether this poses a health risk.  A quick wipe and rinse of the completed dental work vastly decreases whatever risk there might be.
Use a fluoride-containing toothpaste. Floss between teeth at least once a day to remove food particles and bacteria. Use an antibacterial mouth rinse to reduce bacteria that cause plaque and gum disease. See your dentist or oral hygienist every 6 months for a check-up and teeth cleaning. Ask your dentist if a dental sealant is appropriate for you. Dental sealants are a thin, plastic coating that are painted on the chewing surfaces of teeth to protect them from cavities and decay. Eat a balanced diet and limit the number of between-meal snacks. If you need a snack, choose nutritious foods such as plain yogurt, cheese, fruit, or raw vegetables.
