Our Retainer & Mouthguard Services
Retainer Repair & Replacement
If your orthodontic retainer is cracked, warped, or no longer fitting properly, we can repair or replace it to maintain your teeth’s alignment after treatment with Invisalign or other orthodontics.
Occlusal Guards (Nightguards)
Custom-made nightguards protect against teeth grinding and clenching (bruxism), preventing enamel wear, cracks, and TMJ discomfort. Learn more on our TMJ & Bruxism Therapy page.

FAQs – Retainers & Mouthguards
How often should I replace my retainer?
With proper care, most retainers last several years, but they should be replaced if damaged or loose.
Can I wear a sports mouthguard if I have braces?
Yes — we can create a guard designed to fit over braces for protection during treatment.
Will a nightguard stop me from grinding my teeth?
It won’t stop the habit, but it prevents tooth damage and reduces jaw strain.
Are custom mouthguards worth it?
Absolutely — they provide better protection, comfort, and durability than store-bought options.
Can you fix a cracked retainer?
Minor damage can sometimes be repaired, but often replacement is best for maintaining tooth alignment.
Not necessarily — in many cases, it saves time and reduces the need for additional procedures.
