Teeth whitening treatment at home. Put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, and half a teaspoon water. Thoroughly mix then brush your teeth for two minutes.
Dealing with a toothache is the worst thing ever, and damaged roots hurt like hell. What is even worse, the pain harasses you for days. But, toothaches always bother you during weekends or special events.
