Why Do Teeth Have Nerves, and Do Repaired Teeth and Implants Need Extra Care?

Posted in Dental Care, Dental Implant, Dental Surgery, and Tooth Extraction

A tooth may look like a solid, simple structure, but it is actually a remarkable living part of your body. Beneath the hard outer enamel and dentin is a soft centre called the pulp. This pulp contains nerves, blood vessels and connective tissue. So, why do our teeth need nerves in the first place?

The nerves inside a tooth act as an early-warning system. They help you recognize heat, cold, pressure and pain. If a cavity becomes deep, a tooth cracks, or an infection develops, the nerve can signal that something is wrong. That familiar jolt from an icy drink or sharp pain when biting is unpleasant, but it can encourage you to see your dentist before a small issue becomes a more serious one.

The blood vessels in the pulp are especially important while a tooth is developing. They help nourish the tooth and support root formation. Once a tooth is fully developed, however, it can continue to function without its pulp because it receives support and nourishment from the tissues around its roots.

Sometimes the pulp becomes inflamed or damaged because of deep decay, a crack, repeated dental work or an injury. When this happens, root canal treatment may be recommended. During a root canal, the unhealthy pulp is removed, the inside of the tooth is cleaned and sealed, and the tooth is restored with a filling or crown. This can relieve pain, prevent infection and preserve the natural tooth.

Does a Tooth With Nerve Damage Need Extra Care?

Yes—but “extra care” does not necessarily mean a complicated routine. A tooth that has had root canal treatment can still serve you well for many years. It should be brushed twice daily, cleaned between the teeth every day and checked regularly, just like your other teeth.

However, a treated tooth may be more vulnerable to cracking if it has lost a significant amount of its original structure. That is why a crown may be recommended, particularly for back teeth that absorb strong chewing forces. Do not delay a recommended permanent restoration, and avoid using any tooth as a tool to open packages or bite hard objects.

A root canal-treated tooth cannot always give the same warning signs as a tooth with a healthy pulp. New decay, a loose filling, a failing crown or a crack may not cause the familiar hot-and-cold sensitivity. Regular checkups are therefore especially important. Contact Erbsville Dental if you notice pain when biting, swelling, a pimple-like bump on the gums, a loose restoration or a change in how the tooth feels when you chew.

What About Dental Implants?

Dental implants do not have a natural pulp or tooth nerve, and their crowns cannot develop cavities. That does not mean they are maintenance-free. The gums and bone around an implant can still become inflamed or infected, and the implant crown can loosen, chip or wear.

Brush around your implant carefully, clean between it and neighbouring teeth as instructed by your dental team, and attend your recommended hygiene and examination appointments. Bleeding gums, swelling, bad breath, discomfort, loosening or a change in your bite should always be checked promptly.

Whether you have a natural tooth, a repaired tooth or an implant, consistent home care and regular professional care are the best way to protect your smile.
