If you don't like the taste or texture of toothpaste, consider instead using a paste of baking soda and water. This is a great formula for scrubbing the teeth gently while also leaving a healthy feeling to the mouth. Baking soda is all natural, so it won't cause any problems when you use it.
When your dentist has given a recommendation of any antibiotics or even an extraction, do so as soon as you can. Oral infections can spread quickly to other parts of your body if they are not dealt with immediately. Follow your dentist's instructions for caring for infections. This includes taking antibiotics exactly as prescribed.
