Dental Fillings and Their Benefits

Dec 01, 2020

Dental fillings in Downtown Toronto are used to repair small areas of a decayed tooth. By preventing further bacterial infections, the decay is halted.

When applying a dental filling, your dentist removes the decayed portion of the tooth and fills it with a protective filling material that shields the space against additional damage. The tooth’s aesthetic function is also restored.

Fillings are made from various types of materials. The most common include amalgam fillings, gold fillings, composite resin, glass ionomer, and porcelain fillings. Each of the above material has its benefits.

Regardless of the filling type, your dentist at Rusholme Family Dentistry will determine which type is best for after diagnosing the decayed tooth.

  • Dye – It sticks to decayed tooth areas but rinses off on healthy teeth.
  • X-ray – Any decay occurring below the tooth enamel is displayed om x-ray images.
