Dental fillings are a routine procedure used to repair teeth affected by cavities, cracks, or fractures. This process involves removing the damaged tooth material and replacing it with a restorative substance to restore the tooth’s structure and function. Following a filling, careful attention to diet is important to ensure the longevity of the filling and to minimize discomfort.
Foods to Avoid After a Filling
Immediately after receiving a dental filling, certain foods and beverages should be avoided to protect the new restoration and prevent sensitivity. Hard and crunchy foods, such as nuts, hard candies, or ice, pose a risk because they can exert excessive pressure on the newly filled tooth, potentially dislodging or fracturing the filling, particularly if it has not fully set. Sticky and chewy foods like caramels, gum, or dried fruits can adhere to the filling and pull it out. This is particularly problematic for amalgam (silver) fillings, which take longer to harden.
Extreme temperatures also warrant caution. Very hot or very cold foods and drinks can cause sensitivity in the newly filled tooth, as the tooth’s nerve may be irritated from the procedure. This sensitivity is common and can last for several days to a few weeks. Acidic foods and beverages, including sugary items, can contribute to sensitivity and may promote bacterial growth around the filling, potentially leading to new decay. Avoiding chewing on the side of the mouth where the filling was placed, particularly while still numb, helps prevent accidental biting of the cheek or tongue.
Safe and Recommended Foods
A soft diet is recommended immediately after a dental filling to protect the new restoration and minimize discomfort. Foods that are easy to chew and swallow are ideal. Examples include yogurt, mashed potatoes, applesauce, scrambled eggs, and well-cooked pasta. Smoothies are also a good choice as they bypass the need for chewing altogether.
Consuming foods and beverages at lukewarm temperatures helps to prevent triggering sensitivity in the treated tooth. Nutrient-dense options such as pureed soups, cottage cheese, and soft-cooked vegetables like squash or peas can provide nourishment without putting stress on the filling. Taking small bites and chewing slowly on the side of the mouth opposite the new filling further reduces the risk of damage or discomfort.
Navigating the First 24-48 Hours
The timeframe for dietary precautions following a dental filling depends significantly on the type of filling material used. Composite (tooth-colored) fillings harden instantly when exposed to a special blue UV light during the procedure. This means eating is generally safe once the local anesthetic wears off, typically within one to three hours. However, dentists often advise waiting at least two hours before chewing on the filled tooth to ensure comfort and prevent accidental biting of soft tissues while still numb.
Amalgam (silver) fillings require a longer period to fully set and achieve maximum strength, usually around 24 hours. Therefore, it is often recommended to wait at least 24 hours before chewing on the side of the mouth with an amalgam filling and to avoid hard foods for a few days. Temporary sensitivity to hot, cold, or pressure is normal after a filling, regardless of material, and typically subsides within a few days to a few weeks as the tooth adjusts. If sensitivity persists beyond this period or is accompanied by severe pain, contact a dentist. Gentle oral hygiene around the new filling is also important during recovery.
