Fillings, Inlays & Onlays

Dental fillings are probably the most common dental procedure carried out, and at some point in our life, we'll probably need to get a least one of them.

Dental fillings as are used to fill holes in the teeth. These holes are known by many different names such as tooth decay, dental caries or cavities and are caused by bacteria in the mouth.

Every time we eat these bacteria also feed and after eating they produce an extremely strong sticky acid layer known as plaque. When we don’t remove this sticky layer through brushing and flossing, the bacterial acid keeps eroding away tiny amounts of the tooth structure each day until a hole forms in your tooth.




Unlike many other bones in the body, once a hole forms in a tooth, the body cannot repair it. Therefore, to save the tooth from extraction the bacteria needs to be professionally removed, and a hard, tooth-like material known as a dental filling placed.

The team at Belmore Dental Implant Clinic use many different types of dental fillings techniques to treat dental cavities such as​

  • Amalgam

  • Composite

  • Inlay Filling

  • Onlay Filling

The most common fillings are amalgam & composite fillings.

Both amalgam and composite fillings have been around for many years, and although amalgam was adapted for dental use much earlier over 100 years ago, composite fillings gained significant popularity in the last 40+ years.

Amalgam fillings are also more commonly known as silver or mercury fillings and are made up of a mixture of metals such as mercury, silver, copper, tin, and zinc. Composite fillings are more commonly known as white fillings or tooth-colored fillings and are a plastic resin which contains tiny pieces of silica.

Both amalgam and composite fillings are great for repairing small to medium sized cavities. However, there are several advantages in choosing a composite filling over an amalgam.

  • Natural appearance

  • Minimal preparation to the tooth, removing only the damaged portion before placing the filling. With an amalgam filling it is necessary to remove a greater amount of tooth structure.

  • Composite bonds exceptionally well to the natural tooth structure and will create a tight seal to keep out bacteria.

  • Composite fillings are more technique sensitive but offer a superior natural result.

Inlay & Onlay Fillings

When a tooth is damaged too much to place a filling, but not damaged enough to place a dental crown, we end up somewhere in the middle. Large tooth fillings can weaken the tooth structure and could cause the tooth to break, while a dental crown is an unnecessary procedure which will take away more of the tooth than needed.

Inlays and onlays are an alternative option to traditional fillings and fill the treatment gap between needing a large filling and a dental crown. Dental inlays and onlays are the same types of restoration, however, cover different parts of the tooth. An inlay sits inside the center of the tooth while an onlay sits on top of the tooth covering one or more cusps or the entire biting surface.

Life benefits

Fillings & Teeth Whitening C Co Mayo

"I had bad discoloration and needed fillings done. I choose Belmore Dental because I researched different clinics and theirs was the one that impressed me the most. Having the treatment has made me more confident I can smile and show my teeth now, I’m so happy. I am petrified of dentists, and was so scared I had nightmares, the though also kept me up at night knowing that I had to go I was so scared. I went and met for my consultation and cried and they didn't even touch me... they were understanding and so calming which made me feel better coming out. On the day of the procedure have had several fillings and teeth whitening, I was scared but not as much. Even though I was in the chair for 4 hours and I was so calm, I would truly recommend going to Belmore Dental."
