Composite Bonding in Beverly Hills, CA
Medically reviewed by Dr. Kayla Lebeau, DDS
Composite bonding
Bonding is tooth-colored composite shaped directly onto your tooth and hardened with a light. It is the least invasive way to repair a chip, close a small gap or reshape an edge, and in most cases it is finished in one visit with no laboratory stage.
It is also the option we reach for before veneers, because almost nothing is removed. If your enamel is intact, bonding can usually be undone or replaced later. Veneers cannot.
- Usually takesOne visit, 30 to 60 minutes
- NumbingOften none needed
- Tooth removedLittle to none
- LifespanCommonly 5 to 8 years
Bonding is usually the right answer if
- You have chipped a front tooth and want it back the same day
- A small gap bothers you but you do not want aligners
- One tooth is a slightly different shape or shade than its neighbor
- You want to see a change before committing to anything permanent
- An old white filling at the front has stained at its edge
What the appointment involves
- Shade matchWe choose the composite against your own tooth in natural light. This is the step that decides whether the repair disappears or announces itself.
- Preparing the surfaceThe enamel is cleaned and lightly etched so the composite grips. In most cases nothing is drilled and no anesthetic is needed.
- Building the shapeThe composite is placed in thin layers and sculpted by hand, then hardened with a curing light. This is where the skill is: the contour and the edge, not the material.
- Shaping and polishingThe bite is checked, the edge refined and the surface polished until it reflects light the way enamel does.
Bonding, veneers or a crown
- Bonding. One visit, little or nothing removed, and reversible in practice. It stains over years and chips more easily than porcelain.
- Porcelain veneers. Longer lasting and far more stain resistant, but enamel is reduced and that part cannot be undone.
- A crown. Structural rather than cosmetic. If a tooth is cracked or mostly filling, bonding will not hold it together.
If bonding will do the job we will say so, even though it is the cheaper treatment.
Looking after it
- Composite stains where enamel does not. Coffee, tea, red wine and smoking all show at the margins first.
- It does not respond to whitening. Whiten first, then match the bonding to the lighter shade.
- Do not bite nails, pens or packaging with a bonded edge. That is how most of them chip.
- If you grind, wear a night guard. Grinding shortens the life of bonding considerably.
A case from our own practice
A chipped front tooth restored with composite bonding. The edge was rebuilt and the tooth brought back into proportion in one appointment, with no preparation and no waiting on a laboratory.
Does it hurt?
Usually there is nothing to numb, because nothing is drilled. If an old filling is being replaced underneath, local anesthetic is used.
How long does it last?
Commonly five to eight years on a front edge, less if you grind or bite hard objects. It is repaired or refreshed rather than replaced wholesale.
Will it match?
It should be invisible when the shade is chosen properly and the surface polished. Composite is slightly less translucent than enamel, which matters most on very thin edges.
Is it reversible?
In practice yes, where no enamel was removed. That is the main reason to try bonding before veneers.
What does it cost?
Considerably less than a veneer, priced per tooth. You get the figure in writing before we start. Cosmetic bonding is not usually covered by insurance, though a bonded repair after damage sometimes is.
