What is a filling and why do I need one?
Your body’s saliva carries natural defense mechanisms to try to combat the harmful bacteria in plaque, however this isn’t enough to stop tooth decay from forming. It's necessary to practice good brushing and flossing techniques two or more times a day to remove plaque before the bacteria can damage your enamel. Our diet can also play a role in the progression of decay. The more often sugary or acidic foods are consumed, the easier it is for the bacteria to demineralize tooth structure. Even if all these factors are taken into consideration, everyone is different, and some people may be more prone to decay than others. Having professional cleanings and dental exams can help your dentist monitor your oral health and make recommendations specific to your needs.
What types of fillings are there?
The two most common materials used for dental fillings are metal (amalgam) fillings and tooth-colored (composite) fillings.

Other possible reasons for needing a filling include restoring chipped teeth or areas of recession that have lost tooth structure. These areas will often have a "cupping out" appearance and are known as abfractions, or more technically as Non-Carious Cervical Lesions (NCCLs). Abfractions can be caused by a variety of external forces such as grinding, erosion, or toothbrush abrasion. These lesions are not only unsightly, but also prone to decay and your dentist will often recommend "bonding fillings" to cover them up.
What happens after I get a filling?
The numbness from the local anesthesia should wear off within a couple of hours. Until then, it's best to avoid drinking hot or cold liquids, and eating on the side of your mouth with the new filling. Some sensitivity to temperature and biting is normal in the first couple of weeks. If it persists beyond that, it could signal that an adjustment to your filling needs to be made. Continue to brush and floss as normal every day, and don't hesitate to contact your dentist if the pain or sensitivity worsens.
