“How long does dental bonding last on front teeth?”

I have had bonding on some of my patients teeth for 20 years.....with little touch up. These folks practice good oral hygiene, get check up and dont smoke. Drinking alot of coffee or dark tea can stain bonding, as can red wine. Bonding can be touched up from time to time if needed. It is not as strong as crowns or veneers, so often bonding needs a touch up due to chipping

Sorry. Not sure what you mean by dental bonding. Many variations. Ask your American Dental Association dentist.
