Inlays & Onlays

Serving Hannibal and St. Louis, Missouri and Quincy, Illinois areas

Are you tired of the old gray metal fillings or it is time to have some of them replaced? If you need a filling, there are many more choices these days. Traditional metal fillings are compressed into the cavity tightly enough to not fall out, but this does not necessarily mean they have a tight fit or complete seal. Porcelain onlays and inlays are bonded to the tooth, and become part of it. Old metal fillings tend to become loose and even fall out, while porcelain onlays and inlays are firm and durable, being bonded to your natural tooth.

What is the difference between inlays and onlays?

Inlays are smaller, and contained within the cusps of the tooth. Onlays are created for larger areas of decay and extend over to the outside surface of the tooth.

Advantages of inlays and onlays

Metal fillings require more of the natural tooth to be drilled out, even if it isn't decayed. Why? Because the cavity must be shaped such that the tightly packed amalgam will stay put.

No mercury is used in porcelain inlays or onlays. Mercury is a toxin, and while some still maintain that dental mercury is immobilized and safe for the human body, there are many reasons to believe that it can spread through the body. Porcelain is a good choice for those who believe it is better to stay away from mercury.

The porcelain is matched to your tooth color so it's hardly noticeable. Both inlays and onlays will join invisibly with your natural tooth enamel and look like part of your tooth.

The procedure

Porcelain onlays and inlays can be placed during one or two visits.

The traditional process took two visits. During the first visit, the damaged or decayed area is very precisely removed and an impression or mold is taken of the tooth. From this mold, the dental lab will make the onlay or inlay from dental porcelain. In your second visit, Dr. Janes will place the inlay or onlay onto the damaged tooth. After ensuring that your bite is comfortable and the inlay or onlay fits properly, Dr. Janes will permanently bond the porcelain to your existing tooth.

Nowadays, one-visit inlays and onlays are possible using technology, which allows Dr. Janes to manufacture inlays and onlays at his office the same day your tooth is prepared.
