There are many different models to choose from, which can make it extremely difficult to choose one. When you make your choice, you should look for brushes that have soft bristles. Soft bristles are easy on your gums, and they will remove plaque and other debris from your teeth. A small head is also preferred, as it can easily reach hard to get places, such as your back teeth. When the pulp of a tooth dies due to damage or decay, bacteria will begin to grow from the dead tissue that is left. This bacteria will eventually spread from the root of the dead tooth into the tissue that is below and create a pocket of pus - the abscess.
