Can a Toothache Make Me Feel Dizzy?

Brunette woman portraying dizziness from a tooth infectionI started feeling dizzy last weekend and wonder if it has anything to do with my toothache. I had the dentist look at my tooth about a month ago. She examined my tooth and took an x-ray. She said I need a root canal, but I haven’t scheduled an appointment yet. Do you think the dizziness has anything to do with my toothache, or could it be TMJ? Thank you. Tania from Lansing, MI

Tania– If your dentist recommended a root canal treatment after completing an exam and taking an x-ray, it is because your tooth is infected.

Can a Toothache Make You Feel Dizzy?

An untreated toothache can make you feel dizzy eventually. Dizziness results if the condition reaches the nerves in your ear, causing imbalance. A Healthline article on the symptoms of a spreading tooth infection lists dizziness as a signal that the disease is worsening.

Other signs and symptoms of a progressive tooth infection include:

  • Headache
  • Fatigue
  • Chills
  • Sweating
  • Fever
  • Facial swelling
  • Swollen gums
  • Difficulty swallowing or breathing

The infection will continue to spread until a dentist treats it. You can prevent other health issues by seeing a dentist right away.

Is Your Dizziness TMJ?

Dizziness is a symptom of temporomandibular joint (TMJ) disorder. According to the TMJ Association, jaw-joint disorders can cause ear pain, ringing, and dizziness. Still, if your dentist examined your tooth and took an x-ray, please do not assume that your dizziness is TMJ-related. Follow-up with your dentist for root canal treatment.

What Can You Expect with Root Canal Treatment?

Root canal treatment is a painless, routine procedure. If your dizziness is related to your tooth infection, root canal therapy will relieve it. An experienced dentist or root canal specialist (endodontist) will take these steps:

  • Numb your gums and tooth
  • Remove the infection
  • Disinfect the tooth
  • Replace the infected tooth pulp with a root canal filler material
  • Protect the tooth to seal out bacteria
  • Recommend a dental crown if necessary

Call your dentist’s office today for an urgent appointment. Treatment delays allow the infection to spread. Without treatment, you may lose the tooth and need more costly, time-consuming treatment, including a dental implant to replace it.
