Tooth gems are one of the most popular smile accessories in 2025, but a question everyone asks before getting one is: how long do tooth gems really last? The answer depends on application method, adhesive quality, and how well you care for them.
At LaserGlow, we specialize in premium Swarovski-grade crystals and professional bonding tools, so our customers enjoy long-lasting sparkle with minimal risk to enamel.
In this article, we’ll explore tooth gem longevity, part of our Complete Tooth Gems Guide.
Average Lifespan of Tooth Gems
Most tooth gems last 3 to 12 months. With proper application and good oral care, some can stay on for over a year.
- DIY kits: Typically 3–6 months depending on adhesive and technique. Are Tooth Gems Safe?
- Professional application: 6–12 months or longer when applied by a trained dental professional
Factors That Affect Longevity
Several factors influence how long a tooth gem will last:
- Adhesive quality – Professional dental-grade adhesives bond more strongly than generic glues.
- Application technique – Surface prep, curing, and placement affect how well the gem stays.
- Tooth surface – Gems last longer on flatter, smoother teeth than on irregular surfaces.
- Oral habits – Biting nails, chewing ice, or grinding teeth can loosen gems prematurely.
- Diet – Sticky, crunchy, or acidic foods may weaken adhesive faster.
- Oral hygiene – Proper brushing and flossing around the gem helps it stay secure.
How to Make Your Tooth Gem Last Longer
Follow these simple tips to maximize wear time:
- Avoid biting into hard foods for 24–48 hours after application
- Use a soft-bristle toothbrush and brush gently around the gem
- Don’t pick or tug at the gem with fingers or tongue
- Visit a dental professional if your gem feels loose instead of forcing it off
What to Expect When a Tooth Gem Falls Off
Eventually, every tooth gem will come off. Most fall naturally when the adhesive weakens. If yours falls out:
- Don’t panic—your enamel underneath should remain intact if applied correctly
- Schedule a dental check if you notice roughness or sensitivity
- You can immediately reapply a new gem with a fresh kit or schedule a professional reapplication

Why Professional Application Lasts Longer
The biggest difference in longevity comes from adhesive strength and curing technique. Professionals use light-cured dental resin similar to what’s used for braces, ensuring a strong bond. DIY kits can’t always replicate this strength, so results are shorter-lasting.
Final Thoughts
If you want your tooth gems to last the maximum time, invest in enamel-safe gems and adhesives and follow proper aftercare.
