It's complex!: There are many different sealants, but generally two types: resin and glass-ionomer cement. However, each of these types can have many different formulations. For example, resin dental sealants can be clear, white or green, filled or unfilled, have fluoride. They can be hardened with a light, or over time. Contact manufacturers for specific content and percentages.

Composite Resin: Fissure sealants are composed of unfilled or lightly filled composite resins. After the area of a tooth which is at risk of decay is cleaned and etched the resin in bonded into place and serves as a barrier to bacterial acid and impacted food which could predispose the progress of decay. This barrier of composite can only be placed when the incipient decay has been removed. You still must brush. Now you asked for percentages. The companies that produce the various resins we use will all have slightly different ratios, but generally they are around 90% bis gma resins with some fillers and a light stimulated stabilizer which in response to strong light of a particular frequency that shatters the stabilizer bond and drives the chemical reaction from left to right causing the material to set like glass. Dr neil mcleod dds dentistry that lasts - quality that counts.

Depends on brand: The best way to find this information is to go the the website of the company of the sealants brand you are interested in and download the msds sheet for the product. If you are concerned about bpa, ultradent makes dental sealants that are bpa free.
