Tooth pain can be very distressing and adversely affect your daily activities. The throbbing pain from the tooth doesn’t relieve unless you take a medicine. At this point, you may get confused whether cyclobenzaprine can help you get rid of toothache. In this article, I’m going to answer your question, if cyclobenzaprine help with tooth pain.

Before answering the question, I’d like you first to understand what cyclobenzaprine is and how it works so that you can understand things better. 

What is cyclobenzaprine?

Cyclobenzaprine is a muscle relaxant that is used to relieve chronic muscle spasms. It is available in pharmacies under Armix, Flexeril,  flexmid, FusePaq Tabradol, and FlaxePax kit.

Cyclobenzaprine dosage: It is available in the following dosages:

  • Cyclobenzaprine 5 mg is given in elderly patients to keep the dosage low to avoid its side effects
  • Cyclobenzaprine 10 mg is prescribed three times a day. 

Cyclobenzaprine is used to treat pain due to following disorders: 

This muscle relaxer also decreases stress or anxiety following an injury or accident and improves sleep, and calms the nerves. 

How does cyclobenzaprine work?

Cyclobenzaprine enters the brain and relaxes the muscles by inhibiting the nerve impulse responsible for muscle contraction. It is given along with rest and physical therapy to relieve muscle spasms. 

Can cyclobenzaprine help with tooth pain?

No, it doesn’t relieve tooth pain. Toothache is inflammatory in origin and occurs due to bacterial invasion on the tooth’s nerves. The body responds to this attack by producing chemical substances that attack the bacteria to wall off the infection. In doing so, these chemical substances cause damage to the body tissues resulting in pain, redness, and swelling (due to fluid accumulation). 

Patients with wisdom tooth infections often experience difficulty in mouth opening due to muscle spasm of muscles of mastication. This muscle spasm is brought about by the inflammation going on at the site of infection. Therefore, the medications that reduce inflammation resolve the pain. The muscle relaxer (cyclobenzaprine) can be used in conjunction with anti-inflammatory medicines, but muscle relaxants alone may not give you any pain relief. 

A study was carried out where cyclobenzaprine was given to the patients following impacted wisdom tooth surgery to alleviate the post-surgical muscle spasm.

The results found no significant difference in pain relief in the patient who used it. 

The study concluded that there is no need to add an additional medicine to the prescription when the anti-inflammatory medicines (described below) relieve the pain before and after the surgery.

What are safer alternatives to relieve tooth pain?

You can take medications such as panadol, paracetamol, or aspirin instead of cyclobenzaprine for toothache. They resolve inflammation and give you short-term pain relief. However, definitive treatment of toothache involves removal of the source of infection through root canal treatment or extraction of the tooth.

If the pain is not relieved by any one of the above medicines, you can take paracetamol and ibuprofen together. Beware not to take aspirin and ibuprofen together as they belong to the same group and can lead to severe side effects.
