There are many advantages to Resin Onlays. Resin onlays are bonded to the tooth this creates a tight superior fit and restores the tooth to nearly it’s original strength. They can be used in cases where a crown would have been needed in the past. This keeps your tooth stronger because less tooth structure is removed. Resin onlays wear like natural teeth. Since resin onlays are almost invisible they do not need to be placed under the gum line. This is kinder and gentler on the gums. They look great!
