How Long Do Dental Implants Last?

💡 Key Takeaways

• Dental implants typically last 20-30+ years with proper care, with many lasting a lifetime—90-95% are still functioning at 10 years and 80-85% at 20 years
• The titanium implant post itself rarely fails once integrated and can last a lifetime—failures usually relate to gum disease or the crown wearing out
• Crowns (visible tooth portion) typically need replacement every 10-15 years due to normal wear, chipping, or staining—this is expected maintenance, not failure
• Oral hygiene is the single biggest factor affecting longevity—excellent hygiene achieves 95%+ success at 20 years versus 70-80% at 10 years with poor hygiene
• Smoking significantly reduces lifespan—smokers have 80-90% success at 10 years versus 95-98% for non-smokers, with accelerated bone loss and doubled peri-implantitis risk
• Teeth grinding (bruxism) accelerates crown wear to 7-10 years instead of 10-15 years—wearing a nightguard is essential for protecting both crown and implant
• Regular professional maintenance every 6 months (or 3 months with gum disease history) is critical for early problem detection and maximum longevity
• Implants are the longest-lasting tooth replacement option—bridges last 10-15 years and dentures 5-10 years on average, requiring multiple replacements
• Age when implant placed doesn't reduce lifespan—even seniors in their 70s-80s can expect 15-25+ years of function, often never needing crown replacement
• Peri-implantitis (gum disease around implant) is the most common cause of premature failure—preventable with excellent hygiene and professional care
• Crown replacement at 10-15 years costs £500-1,500 and is normal maintenance, not failure—much simpler and cheaper than a new implant
