What Kills A Tooth Nerve? – Anatomy of a Toothache

May 06, 2021

Reasons for tooth abscesses consist of decay (cavities), gum illness, a split tooth, or injury. When several of these conditions exist, germs have a chance to get in the tooth, contaminate the nerve tissue, and will ultimately eliminate the nerves and blood supply to the tooth– basically eliminating the tooth.

What is a tooth nerve?

The term “tooth nerve” is used to describe the nerve endings that are close to the surface of the teeth and under the gums (dermal papillae) that feed into the pulp chamber in the tooth. The pulp of the tooth is the important body of tissue of the tooth that stores the tooth’s cells. The pulp is the center of the tooth that feeds the microscopic teeth like cusps and crowns. The pulp also provides many physiological functions: it contains the blood supply to the nerve cells, oxygen to the cells, and even fluid that helps dissolve dead and decaying tooth matter. The blood supply to the tooth nerve tissues is provided by capillaries, which are small vessels that have the ability to transport the necessary nutrients for cell growth and circulation.

What Causes Tooth Nerve Problems?

Nerves in teeth do not regenerate in a state where they have been cut off. As a result, damage to the nerves means that if one or more teeth are affected, the nerve needs to be regenerated. Sometimes this requires multiple procedures before a nerve is actually regenerated to the point where it can take up its normal function again. When a tooth is gummed up by bacteria and cannot receive adequate blood flow, the nerves that normally run through the gum will go dormant. The nerve will not receive any more blood flow, and it will be like an almost dead branch of a tree; the tree will slowly wither away, leaving no other function. A nerve cannot survive without blood to supply it. Hence, the nerves need to be cleaned out so that they can be functioning again.

What can you do to avoid tooth nerve problems?

It is not possible to prevent tooth decay, as it is inborn, but it is possible to prevent the cause of the decay from ever occurring in the first place. That is, by proper diet and by avoiding products that are an aspiration of bacteria and their toxins. The liver, in this process, filters out bacteria and toxins that are not able to be digested and by keeping out these dangerous items, no bacteria and toxins will ever be able to grow and eat away at the soft tissue of the tooth. If you are having a problem with a rotting tooth that just won’t give up the tooth, then brushing with a toothpaste containing aluminum as it prevents bacteria from sticking to the tooth’s surface and thus helps keep bacteria at a minimum.

What happens when a tooth nerve is damaged?

As mentioned earlier, tooth injuries can be the root cause of tooth abscesses. People who suffer from sleep apnea, snoring, obesity, gum disease, gingivitis, or periodontal disease can cause damage to the tooth as they inhale bacteria, plaque, food and debris into their lungs. These bacteria or plaque containing germs enter the mouth and become lodged in the gums. When these germs enter the mouth and attach to the tooth, this can cause an infection. The mouth and oral cavity contain six different types of bacteria that can cause an infection in the mouth. These bacteria include Corynebacterium and Streptococcus mutans which are the most common oral pathogens.


Therefore, those who consider themselves to be healthy have a big advantage over those who do not. It is important for one to realise the root cause for the onset of tooth pain. If one is not bleeding, then there is not necessarily a real problem, but rather a fear of having a problem. It is when a patient feels a toothache and hears that it will just take time to heal that they become paranoid. This is what causes much of the finger-pointing, frustration and distrust of health care workers. Doctors are just as vulnerable as anyone else. We should work to eliminate as many variables as possible and not believe every little symptom or twinge we may experience.
