Smoking after custom mouthguard: the short version
Being fitted for a custom mouthguard does not restrict smoking, since it is an impression or scan and not a treatment. Nothing in your mouth is healing. The guard itself should never be in while smoking: the soft plastic absorbs smoke, yellows, and holds the smell and residue against your teeth and gums the next time you wear it. For an athlete, smoking also works against the reason for owning a sports guard.
What is actually going on
Mouthguards are made from a flexible plastic that is slightly absorbent. Smoke particles and tar lodge in the surface, turning a clear guard brown and leaving a taste that cleaning does not fully remove. Heat is a second problem: the material is shaped by warming it over a model of your teeth, so a lit end or hot smoke close by can soften it and distort the fit. A night guard for grinding sits on the teeth for hours, so any residue on it, or on teeth that were not brushed first, is held against enamel and gum all night. One more point for night guard wearers: nicotine is a stimulant, and tobacco use is associated with more clenching and grinding during sleep, the very habit the guard is there to protect against.
Getting through the wait
A mouthguard fitting is an impression or a scan, so nothing in the mouth is healing and no wait applies. The first hour may involve a putty aftertaste and nothing more. The questions that matter concern the guard, not the appointment: it is molded plastic that soaks up odor and softens with heat, and it should never be in the mouth around smoke. For anyone who plays sport, tobacco also works against the fitness the guard is there to support. If the fitting has you thinking about cutting back, your dentist can direct you to a doctor or pharmacist for support.
Smoke After Custom Mouthguard: What You Need to Know
Wait time
A custom mouthguard does not usually add a waiting period of its own for smoking. That is not a recommendation: tobacco, nicotine, and cannabis all work against your teeth and gums, and your dentist can tell you what applies to you.
Why
The guard itself sets no wait
Tips for Smoking After Custom Mouthguard
- 01Keep the guard in its ventilated case away from smoke; it picks up odor from the air as well as from the mouth.
- 02Brush your teeth before a night guard goes in so residue is not sealed against them for hours.
- 03Clean the guard with cool water and a soft brush or the cleaner your dentist recommended; hot water warps it.
- 04Bring the guard to dental checkups so the dentist can check its fit and condition.
Common mistakes
- 01Leaving a night guard in for a last cigarette before sleep. The plastic takes up smoke and holds the residue against teeth and gums for the next seven or eight hours.
- 02Boiling or scalding a smoke-stained guard to freshen it. The guard was shaped with heat, and hot water reshapes it, so it comes out smelling cleaner and no longer fitting.
- 03Storing the guard loose on a car dashboard or in a jacket pocket with a cigarette pack. It absorbs odor from the air and from tobacco flakes, and sun through a windshield can distort it.
