How long can I wait to get a root canal if I don’t feel pain?

Posted on by .

I’m trying to figure out when I need a root canal if I don’t feel any pain. I am job searching, and if the tooth can wait, I would prefer to postpone it. My left first molar tooth is discolored, and my dentist says that the tooth is infected. She wants to complete a root canal and cover the tooth with a crown. If the tooth does not hurt, is this really urgent? – Thank you. Marcus from OK

 

Marcus,

Thank you for your inquiry. Your dentist is right; a dark infected tooth requires treatment.

Why Is Your Tooth Turning Dark?

Your tooth can turn dark from infection. When the tooth pulp (the living tissue inside) dies, it turns dark, and the discoloration shows through your tooth. Tooth pulp contains tissue and nerves, so you will not feel pain if the tooth is dead.

Can You Delay Root Canal Treatment?

Although you do not feel pain, your tooth infection is lingering. A dark tooth means that you have probably had the infection for some time. It can spread into your bone or your bloodstream. Although you may not feel pain, other symptoms of a long-term tooth infection include:

  • A foul taste or smell in your mouth
  • Difficulty breathing or swallowing
  • Swelling in your face or cheek
  • Tenderness or swelling under your jaw or in your neck (lymph nodes)
  • Fever
  • Gum disease
  • Dehydration
  • Stomach pain
  • Fatigue

A dead tooth is an urgent matter because the infection can poison other parts of your body.

What Can You Expect with Root Canal Treatment?

Root canal treatment is painless, but your tooth will be weak. And your dentist must protect it.

  • Painless – A skilled dentist uses a local anesthetic for painless root canal treatment. But if your tooth is dead, you will not feel any nerve pain.
  • Foul smell – A tooth that has been dead for years has a bad smell. You will probably notice it and be happy that your dentist removed the infection.
  • Protecting the tooth afterward – If you have a strict budget, you do not have to get a dental crown right away. Instead, ask your dentist to complete the root canal and protect your tooth until you can afford a crown.

After the dentist completes the treatment, you will probably feel better. You might have mild symptoms that you ignored or did not associate with your tooth.

Best wishes.

Horrible toothache and headache, but my dentist sees no problem

Posted on by .

In January, my dentist did a root canal on an upper right molar tooth. The tooth felt better afterward but has not been symptom free. Two weeks ago, I felt a flare-up of pain that felt like it affected the tooth next to the root canal tooth, and I have a headache, too. I returned to my dentist on Monday, and she took x-rays. She says that both teeth look fine. She suggested that I see a neurologist. I do not think my dentist is investigating enough. Why a neurologist?  Thank you. Bryson from Arkansas

Bryson,

Although Dr. Perry would need to examine your tooth and x-ray to give you an accurate diagnosis, we can offer insight that might help you decide what to do next.

Pain from a tooth that looks healthy

It is not uncommon to feel pain in a tooth that looks healthy in a visual examination and on an x-ray. Some causes of tooth pain include:

  • Referred pain – Infection from a tooth can refer to an opposite upper or lower tooth. Or it can feel like the pain is coming from an adjacent tooth. But pain does not refer from one side of the mouth to the other.
  • Neuralgia – Chronic nerve pain can transfer in your face, jaw, teeth, or gums. Although the condition is usually not the cause of a toothache and headache, a nerve problem can feel like a toothache. That is why your dentist recommended that you see a neurologist.
  • Infection – A sinus infection can cause headaches and pain that feels like a toothache. The maxillary sinus is near the roots of upper teeth and can press on the roots, causing a toothache sensation. Sinus pain can also transfer to a lower tooth.
  • Other health issues – Some conditions that can feel like a toothache and cause headaches include jaw pain, clenching or grinding your teeth, or gum disease. According to the American Migraine Foundation, TMJ (temporomandibular joint) disorders can contribute to chronic headaches.

If you feel that your dentist is not a good listener or rushed for a diagnosis, we suggest getting a second opinion. You can get a second opinion from another dentist or a root canal specialist (endodontist).

Are your tooth pain and headache a dental emergency?

Sudden or lingering toothache – If you have a sudden or lingering toothache and headache but no recent dental work, see a dentist right away. Toothaches are most often a symptom of infection.

Toothache after dental work – If you had root canal treatment or other dental work that seems to be your pain source, contact the dentist who completed the treatment. If the pain persists beyond the healing period or gets worse, consider it an emergency.
