There will be new items called toothbrush and toothpaste!
Overtime, you teeth start to decay, making eating food take longer and longer, and less effective. Eating will speed up this process. To undo this, you must brush your teeth twice a day, and floss once a day. You can use string to floss your teeth. To make things more fair, other mobs also brush and floss their teeth! If you neglect your teeth too much, they might just fall out and you can. no longer eat.
Villages will have a new building called a dentist office, where you come in and check your teeth. If your teeth have cavities, you must come in soon or your teeth falls out! When villages take care of you're teeth, you can watch them use their tools. Sometimes, the player takes some damage and kicks around and screams!
After you visit the dentist office, the dentist gives you a lollipop, which gives you 5 hearts, and speeds up tooth decay.
