Fresh and Clean: How to Clean Under Fixed Bite Plates and Orthodontic Appliances
Orthodontic appliances like fixed bite plates are fantastic for correcting your smile, but they come with one major challenge: keeping them clean. Because these appliances are bonded directly to your teeth, food particles and plaque love to trap themselves underneath. If left uncleaned, this can lead to bad breath, gum irritation, and tooth decay. Fortunately, keeping your appliance sanitary does not have to be a difficult chores.
The Ultimate Cleaning Tool: The Monoject Syringe
The most effective way to clean under a fixed bite plate is by using a plastic utility syringe, often called a Monoject syringe. This simple, non-electric tool allows you to blast away trapped food in less than 30 seconds.
To use it effectively, follow these quick steps:
- Fill the syringe with clean, warm water.
- Lean directly over your bathroom sink.
- Position the curved tip right under the edge of the appliance.
- Press the plunger firmly to flush out the debris.
Repeating this a few times after meals will instantly keep your mouth feeling fresh and sanitary.
Why You Should Avoid Floss Threaders
Many patients naturally think about using a floss threader to slide underneath the plastic plate. While this seems logical in theory, it is highly discouraged in practice.
Bite plates are often held in place by tight contacts. Forcing a thick plastic floss threader under the appliance puts immense pressure on the dental cement. This creates a very high risk of accidentally debonding or dislodging the appliance completely. Stick to water pressure instead to avoid an emergency trip back to the orthodontic office.
Quick Cleaning on the Go
Maintaining your dental hygiene can feel tricky when you are away at school or work. You cannot exactly carry a syringe to every public restroom, but you still need to clear out food after lunch.
The easiest on-the-go trick is the “swish and spit” method. Simply take a water bottle with you into the restroom. Take a large gulp of water, swish it vigorously around your mouth to loosen up food particles, and spit it out. This quick fix will hold you over until you can get home to your regular cleaning routine.
