Replacing Dental Sealants As an Adult?

That's awesome to know and it seems you take good care of your teeth because the typically do not last as long. Keeping it clean by brushing with an electric toothbrush and flossing daily, it will help to maintain the one are intact. There are other options like Preventive resin restorations (PRR) that are adult sealants. Very easy, fast and comfortable procedure that do not need anesthetic because is very conservative approach. The cost is much less than a regular filling , ask your dentist if he provides the service. But meanwhile, keep them clean!

If in fact your sealants are wearing away and only a small amount of it remains I would get them replaced as decay can get under them if they are leaking.  Speak to your dentist and get their opinion

 

Replacing a sealant is a lot better then having to replace a filling. It sounds like your teeth did very well with sealants.  I would continue to protect them by replacing the sealant.  

You certainly can have your sealants replaced at your age, or any age for that matter.  The only requirement is that the teeth do not already have fillings in them.

At your age the enamel is completely formed and mineralized. The major thing to prevent the decay is to keep good oral hygiene and use electric tooth brush and waterfloss with mouthwash.
