Composite bonding means adding tooth-coloured filling material to the surface of a tooth and shaping it by hand to repair a small chip, close a gap or improve a tooth's shape. It is usually done in a single visit, with very little or no removal of tooth structure. But it is not the best option for every case: it stains and chips more easily than porcelain veneers, and it needs care and maintenance.
Bonding is mostly used for small to moderate cosmetic changes to the front teeth, such as:
Your dentist first chooses a shade of filling that matches your teeth, then roughens the tooth surface slightly with a special gel so the material bonds well. The material is then added layer by layer, shaped by hand and hardened with a special light, and finally polished until its shine is close to that of a natural tooth.
In most cases no anaesthetic is needed, because the work is on the enamel surface. A session may take from about half an hour to an hour per tooth, depending on the case. If you are thinking about whitening, it is best to do it before bonding, because the filling material does not respond to whitening and keeps its shade.
Both improve the look of your teeth, but there are important differences to weigh with your dentist:
How long bonding lasts depends on its position, its size and your daily habits. A small bond closing a gap may last many years, while one covering the biting edge of a front tooth takes more force.
Things that shorten its life include nail biting, opening packets and bottles with your teeth, chewing ice or pens, and grinding at night without a guard. Drinking a lot of Arabic coffee and tea, and smoking, also affect its colour over time. The good news is that polishing at follow-up visits restores much of its shine.
Care is much the same as for your natural teeth, with a little extra attention:
It usually needs very little or no removal of enamel, so it is considered a conservative option, and in many cases it can be adjusted or removed later.
Yes, it can gradually stain with coloured drinks and smoking and lose some of its shine. Regular polishing improves its appearance, and it may need renewing after some years.
Yes, for example after a front tooth is chipped in an injury. It is a good option because it is conservative and can be adjusted as the child grows. Your dentist will decide what suits the age and case.
For small gaps it may be enough. If the gaps are large, the teeth are out of line or the bite is affected, braces may be more suitable, or the two may be combined.
See a dentist if part of a front tooth breaks or leaves a sharp edge, if a gap or a differently shaped tooth bothers you, if an old filling has stained or its edge has lifted, or if you have sensitivity after a chip. An assessment will show whether bonding suits your case or whether another option would serve you better.
