Dental sealants can last up to 10 years under the right conditions. However, if you grind and clench your teeth, this can shorten their lifespan. It also depends on how much hard food you eat. The more hard food that you eat, the less likely your sealants are to last 10 years.
A single tooth getting a dental sealant applied to it is $50. Typically molars are the only teeth that get sealants applied to them so you can expect to pay around a maximum of $600 for a full sealing procedure.
Until you get used to chewing with your new dental bridge avoid hard foods and taking large bites. Be sure to avoid really sugary foods because they contribute to plaque building which will allow for unwanted bacteria to buildup on your bridge.
The better you take care of your teeth, the longer your bridge will last. You do not have to do anything outside of normal care for you teeth. Just make sure practicing consistent daily tooth care. This includes brushing and flossing your teeth as well as dental check ups and cleanings every six months.
A dental bridge can replace can one tooth or as many as three missing teeth that sit next to each other on either side.
