The lifespan of dental bonding is influenced by multiple factors, including the specific location of the bonded tooth, your dietary choices, and your oral hygiene routine. On average, dental bonding can last between 4 to 10 years, or even longer with proper care. During your routine dental check-ups, your dentist will assess the condition of the bonding and address any signs of wear and tear by applying additional composite resin to maintain its strength and durability.
