A dry socket is a condition where the blood clot that forms after an extraction detaches itself from the socket walls. Sometimes, the clot will dissolve, leaving the bone exposed to food, the weather, and even saliva. Once the bone is exposed, it can become inflamed. The inflammation that occurs is very painful, often times being a deep pain that makes you feel as if you are dying. Using various tools and equipment, he will go down inside of the tooth and scrape away the nerves and dead pulp. This is a very effective procedure, although very time consuming as well. In most cases, a root canal can take several hours, although it is the only way to stop the dying pulp and save the tooth. If you have sensitive teeth now, you should try using an electric toothbrush such as the Sonicare advanced. Although you may have sensitive teeth now, there are ways you can help to improve your gums and your teeth. There are several toothpastes out there on the market that contain potassium nitrate, which helps to reduce pain and discomfort associated with sensitivity. Cracks can make your tooth feel as if it is exploding, as they expose the dentin and nerves to the air and anything else you put in your mouth. If you don t get them fixed, they will get worse, possibly leading to your tooth breaking off at the gums. Pulp irritation is another cause of toothaches, as it occurs after dental treatment. Dentists were just starting to come around, although they didn t have near the equipment and sophistication that they have these days. Even though teeth were pulled during these times, it normally happened with alcohol to numb the pain then pliers to remove the tooth. Throughout the course of time, herbs have proven to be very effective with stopping toothache pain. 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. You should also remember to replace your brush every couple of months, or when it starts to show signs of wear.
