What is Diclofenac?

Diclofenac is a type of medicine known as a non-steroidal anti-inflammatory drug (NSAID). Its used widely across the UK for managing pain and inflammation, especially in conditions like arthritis, back pain, and injuries.

Available under brand names like Voltarol, Diclofenac comes in different forms, including oral tablets, gels, suppositories, and injections. While the topical gels are mostly for joint and muscle issues, the tablets are sometimes used for dental or post-surgical pain.

How Does Diclofenac Work on Toothache?

To understand how Diclofenac helps, its important to know whats going on when your tooth hurts. Most toothaches are caused by inflammationwhether from decay, infection, gum disease, or trauma. Inflammatory substances in your body cause swelling and send pain signals to your brain.

Diclofenac works by blocking enzymes (COX-1 and COX-2) responsible for producing prostaglandinsthe chemicals that trigger pain and inflammation. By reducing prostaglandin production, Diclofenac lowers inflammation and dulls the pain.

In cases of swollen gums, dental abscesses, or even post-wisdom tooth extraction discomfort, Diclofenac can be particularly effective. It offers relief not just from the pain itself but from the underlying inflammation that often makes toothaches worse.

Diclofenac vs Other Painkillers for Toothache

Final Thoughts: Relief or Risk?

Diclofenac can help ease toothache, particularly when the pain is caused by inflammation. Its a strong medication that offers effective short-term relief but isnt suitable for everyone and shouldnt be used as a long-term fix.
