Composite bonding typically lasts several years, but exact duration depends on a few key factors. Direct answer:
- Most dental sources suggest a typical lifespan of about 3 to 10 years for composite bonding, with many practitioners citing 4 to 8 years as a common range. The wide spread reflects differences in materials, technique, bite forces, and aftercare.
Key factors that influence longevity:
- Location in the mouth: front teeth usually endure less biting pressure than back teeth, often giving longer-lasting results on front teeth.
- Material quality and resin type: higher-quality materials and proper bonding technique contribute to longer wear resistance.
- Habits and lifestyle: smoking, consuming highly staining or acidic foods, and parafunctional habits (like grinding) can shorten bond durability.
- Oral hygiene and maintenance: regular brushing, flossing, and avoiding biting hard objects help extend bonding life.
- Cosmetic expectations: bonding is not a permanent replacement; it is designed to be repairable or replaceable if needed.
Practical guidance to maximize longevity:
- Avoid biting hard foods or objects (ice, pens) on bonded teeth.
- Maintain excellent oral hygiene and routine dental checkups.
- Schedule timely touch-ups or replacements if you notice chipping, discolouration, or rough texture.
If you’d like, I can tailor these estimates to your situation (for example, the specific tooths involved, bite pattern, and your maintenance routine) and compare several reputable sources side-by-side.
