How do get rid of a tongue splinter?

Depending on how big the splinter is, you may need to see a doctor. However, you can begin to help the process at home. At a pharmacy, buy a bottle of hydrogen peroxide. At home, use the bottle cap for measuring. Put one CAP full (tiny, tiny amount) of hydrogen peroxide in a small glass. Add warm water to this. Have a second glass of water with only warm water-- no peroxide.

Sip a small amount of the peroxide water and swish in your mouth but do not swallow it. NOTE: this mixture will cause a foaming to occur. Keep spitting out the foam-- you can use the fresh water to rinse. Repeat with the peroxide mixture one more time. Spit, do not swallow. Follow with fresh water rinse and spit it out. You will feel bubbles in your mouth--that is ok. Just keep spitting it out.

You can repeat this rinse twice a day. Try not to pinch your tongue or play with the spot. If it is a tiny splinter, your body should send macrophages to the area to clean up the injury and push out the splinter (much like after a tooth extraction). But if the splinter is long or the site develops pus, a doctor may need to remove it for you. Do not try to remove it yourself.
