Considering Gingival Flap Surgery? Here’s What You Should Know

Causes and Consequences of Teeth Grinding
April 13, 2022Once patients have undergone orthodontic treatment, they’ll most likely be advised by their orthodontist to use a retainer in order to maintain that straight, beautiful smile.
In many cases, patients will need to wear their retainer constantly for six months up to a year in order to see the best results. After that initial designated amount of time, orthodontists typically recommend nightly wearing to prevent shifting teeth.

But should you be wearing the same retainer this entire time? Retainers don’t last forever, so how do you know when it’s time for a replacement?
The following signs indicate you might need getting a new retainer to stay on top of your dental maintenance.

Visible Cracks or Damage in Your Retainer
Over time, retainers can weaken and show signs of damage. Even small imperfections can affect their effectiveness. Here’s what to look out for:
- Signs of Wear and Tear: If you’ve had your retainer for close to a year or longer, you may start noticing the material has worn down.
- Small Cracks, Chips, or Dents: Even if the damage seems minor at first, it will only get worse over time.
- Loss of Structural Integrity: A damaged retainer will eventually lose its ability to function properly.
- Ineffectiveness: When compromised, your retainer becomes nothing more than a piece of wire or plastic in your mouth, failing to keep your teeth straight.
Your Retainer is Warped and Doesn’t Fit
Over time, retainers can lose their shape and no longer fit properly. Here are some common reasons why:
- Ineffectiveness: A retainer that doesn’t fit properly won’t do its job—if this happens, it’s time to get a replacement.
- Heat Damage: Cleaning your retainer in the dishwasher or with very hot water can cause it to warp.
- Infrequent Use: If you haven’t been wearing your retainer regularly, your teeth may start to shift, affecting the fit.

Persistent Calcium Buildup?
Even with regular cleanings, calcium buildup can form on your retainer. Here’s why it’s a problem:
- Ineffective Cleaning: If denture cleaner or a vinegar soak can’t remove the buildup, it’s time to replace your retainer.
- Visible White Patches: Large white “dirty” areas may appear, indicating calcium deposits.
- Bacteria Growth: Buildup can become a breeding ground for bacteria, increasing your risk of throat and mouth infections.
You Lost Your Retainer
This one’s obvious, but important. Life happens, and just as you may have lost your phone, keys, or wallet in the past, you might also lose your retainer.
If you lose your retainer, you should make it a top priority to get a new retainer as soon as possible. The longer you go without a retainer, the greater chance your teeth will move out of place.
To avoid the chances of losing your retainer, establish a good routine and place you put your retainer each time you take it out.
