Emergency? If you have trouble breathing or swallowing, swelling that is spreading toward your eye or neck, a fever with facial swelling, or bleeding that will not stop, call 911 or go to your nearest emergency room immediately. Full disclaimer

Rinsing your mouth after custom mouthguard: the short version

You can rinse immediately after a mouthguard fitting; there are no restrictions. The visit involves impressions or a scan and leaves nothing to heal. Rinsing is mostly useful for clearing the taste and stray bits of impression material, and later, once you have the guard, it becomes part of looking after the guard itself.

What is actually going on

Impression putty sets to a rubbery solid, and thin tags of it can stay between teeth or under the gum edge, tasting faintly minty or chemical. A good swish with water followed by floss usually finds them. If a tray pressed on your gums or made you gag, your throat and palate may feel irritated for an hour, and cool water helps. When the guard arrives, rinsing applies in both directions. Rinse your mouth before the guard goes in, after brushing, so it is not sealing toothpaste and debris against your teeth. Rinse the guard under cool running water each time it comes out to wash off saliva before it dries into a film. Some makers warn that soaking guards in alcohol-based mouthwash can harm the material over time.

The first time, step by step

A fitting leaves nothing to protect, so rinse whenever you like. Straight after impressions, a couple of firm swishes with water clear most of the taste; check between the front teeth and behind the last molars, where putty likes to hide. After a digital scan there is nothing to rinse away at all. Once the guard is yours, the first night sets the habit: brush, rinse your mouth, seat the guard, and in the morning wash it off before it dries. If your mouth feels sore, dry, or oddly coated after wearing it, tell your dentist, who can check the fit and advise on cleaning.

Tips for Rinsing your mouth After Custom Mouthguard

  1. 01Swish and floss after the impression visit to remove leftover putty between the teeth.
  2. 02Rinse the guard in cool water as soon as you take it out, before saliva dries on it.
  3. 03Avoid hot water for the guard; warmth can soften it and spoil the fit.
  4. 04Ask your dentist which cleaning products are approved for your guard material before soaking it in anything.

Common mistakes

  1. 01Rinsing the mouth with mouthwash and popping the guard in while the teeth are still wet with it. The guard holds the rinse against the gums for hours, which can leave them irritated by morning.
  2. 02Giving the guard a quick rinse and sealing it wet in a closed box all day. Damp plastic in an airtight case grows a film and a smell; a ventilated case and air drying prevent it.
  3. 03Rinsing a sports guard in the drinks bottle or a shared water cooler at the field. It contaminates the water for everyone and does little for the guard; a rinse under a tap afterward is enough.

Frequently Asked Questions

Table 3 — Common questions

I found a piece of impression material in my gum days later. Is that a problem?

It happens occasionally. A small rubbery fragment between the teeth usually comes out with floss and causes no harm. If a piece seems lodged under the gum and you cannot remove it easily with floss, or the gum there is sore or swollen, do not dig for it. Call your dentist, who can lift it out in moments.

White spots have built up on my guard even though I rinse it. What are they?

Usually mineral deposits from saliva, the same material as tartar on teeth, which rinsing alone does not prevent. Gentle daily brushing of the guard slows it. Do not scrape it or use hot water or bleach. Your dentist can clean the guard professionally at a checkup and tell you which soaking product is suitable for the material.

Is it okay to rinse with salt water if the new guard rubbed my gum?

Yes, warm salt water is a simple comfort for a rubbed gum or cheek and can be used a few times a day. It eases the sore without fixing the cause. A guard that leaves the same sore spot each time has an edge that is too long or too sharp, and your dentist can trim and polish it in a short visit. Do not trim it yourself.
