A porcelain onlay is similar to a dental crown in that it is designed to restore a tooth that is broken down so much that a filling is not enough to fix it. If too much of the tooth is missing, the tooth could fracture. A porcelain onlay covers most or all of the chewing surfaces of the tooth and strengthens it so that it won’t fracture. 

Dental CLinics in Manila provide and offers the best quality One advantage of porcelain onlays is that they preserve more of the natural tooth structure. There is a feeling many dentists have that if the tooth structure is healthy, it is best to leave it alone if possible.

A second advantage is that, since they don’t go down to the gum line, there is no chance of them irritating the gum. Crowns can cause gum irritation and in some cases can even contribute to gum disease. Also, since they don’t go down to the gum line, it is easier to keep the margin (that line where the porcelain onlay or crown ends and the tooth begins) clean. The margin is out in the open where you can easily brush it. The margin of a crown is the place that is most vulnerable to recurrent decay. Thus, porcelain onlays are less likely to get new tooth decay.

 

Third, porcelain onlays, being made entirely of porcelain (or another ceramic), are very esthetic. They look extremely natural.
