Teether

It has the effect of reducing the pain of irritable wisdom teeth.

[1] Most modern teethers are silicone, but can also be made of wood or rubber.

Some teethers are filled with a fluid or gel that can be frozen or refrigerated.

[3] Studies found that chewing a teether may make teething children calmer and happier, less stressed, and less cranky.

[5][6][7][8] Teethers filled with liquid have also been recalled because of bacterial contamination.
