How long does dental bonding last?

The short answer: about 3 to 7 years

Dental bonding often lasts about 3 to 7 years. Some bonding holds up longer and some chips sooner. Dental sources commonly quote a range like this, and Cleveland Clinic notes that bonding is not as long-lasting as veneers or crowns.

The good news is that bonding is easy to repair. A small chip can often be fixed in one short visit, so a worn spot does not mean you start from zero.

Where you stand in that range depends on you. A person who does not grind, does not chew on hard objects and sees the dentist twice a year may get 7 years or more. A person who bites nails and grinds at night may see a chip in the first year or two.

What bonding is

Bonding is a tooth-colored resin that your dentist shapes onto your tooth to fix a chip, close a small gap, cover a stain or lengthen a short tooth. It is usually done in a single visit, and Cleveland Clinic says it removes little or no enamel.

Because it is built right on your tooth and not made in a lab, bonding is a flexible fix. It is also the reason it wears faster than porcelain.

Bonding is also used to cover small areas of root exposed by gum recession, and it can protect worn spots near the gum line. In those cases, the bonding is not for looks alone. It also helps reduce sensitivity.

What makes bonding chip or wear

The biggest factor is where the bonding sits. Bonding on the biting edge of a front tooth takes more force than bonding on the side of a tooth. A chip at the edge is the most common failure.

Habits matter next. Biting nails, chewing ice or pens, opening bottles with your teeth and grinding at night all put force on the resin. Grinding is a leading cause of early chips.

Gap-closing bonding on the sides of front teeth usually holds up better than a corner rebuilt after a break. Larger bonded areas have more chance of chipping off, because there is less tooth to hold on to. Your dentist can tell you which category your tooth falls into.

Age of the bonding matters too. Even with great care, the resin slowly wears and loses its shine. A routine polish at your cleaning can bring some of it back.

Why bonding stains

The resin is not as smooth or dense as porcelain, so it picks up color from coffee, tea, red wine, dark sodas and tobacco. Cleveland Clinic notes that bonding does not resist stains as well as porcelain restorations.

Stains build slowly. A cleaning and polish can bring the surface back. If the color is dull all around, your dentist may polish or refresh it.

If you drink coffee every day, plan for a polish at each cleaning. Your hygienist can remove the surface stain, and you may see the shade brighten right away. If stains go deeper than the surface, you may need a replacement for the best match.

How to make it last

A few habits go a long way:

The most common issue patients bring in is a small chip on the edge. It rarely hurts, and it can be fixed quickly. Come in within a few weeks, though, since a rough spot can catch your tongue or collect plaque.

Try not to use your front teeth to tear food. Cut meat and fruit with a knife, and bite with your side teeth. Small changes like this protect the edge of your bonding every day, and they cost nothing.

• Brush twice a day with a soft brush and floss daily
• Do not bite nails, pens or ice, and do not use teeth as tools
• Rinse with water after coffee, tea and wine
• Wear a night guard if you grind your teeth
• Get a cleaning every six months so your dentist can polish the surface and check the edges
• Cut hard foods like whole apples or crusty bread before biting

Repair or replace?

Small chips and rough edges can usually be repaired. Your dentist adds a little resin, reshapes it and polishes it. This is quick and often needs no numbing.

If the bonding is badly stained, loose or has cracked through, it is usually replaced. If you keep chipping the same tooth, ask about a longer-lasting choice like a veneer or crown. Do not wait on a loose piece, since food and bacteria can get under it and cause decay.

It also helps to take pictures of your bonded teeth. A dull or yellow look can sneak up on you, and photos show it clearly. Share them with your dentist at your next visit.

Ask your dentist what the repair would involve before you agree to it. Many repairs are quick. Others take longer if the bonded area is large, or if decay is found under the bonding. A clear plan saves surprises.

What a visit looks like

Bonding is a simple visit. Your dentist picks a shade that matches your teeth, lightly roughens the surface, adds the resin, shapes it, hardens it with a light and polishes it. Most single teeth take about 30 to 60 minutes.

You can eat and drink right away, though dentists often suggest avoiding dark foods and drinks for the first two days.

Before bonding, your dentist may show you a shade guide and match the resin to your natural teeth in daylight. If you plan to whiten, do it first, since the resin will not lighten later. Ask about the timing so everything matches.

Many patients are surprised by how little bonding hurts. If there is no decay, there is often no need for numbing. You will still feel pressure and may hear the drill or the sound of polishing, which sounds worse than it feels.
