Botulinum Toxin Treatment

Bruxism (Teeth Grinding), Botulinum Toxin

Bruxism, or the involuntary grinding and clenching of teeth, is an increasingly common condition that often goes unnoticed for a long time. In addition to wearing down the enamel and putting strain on the temporomandibular joints, bruxism can cause tension headaches, facial pain, and excessive jaw muscle tension. It is not just an oral health issue, but also one that can significantly affect everyday comfort and well-being.

Botulinum toxin, also known as Botox, is a key treatment for bruxism. This neurotoxin, produced by the Clostridium botulinum bacteria, is widely used in both aesthetic medicine and the treatment of various conditions. In the case of bruxism, Botox works by relaxing the overly tense masseter muscles, which not only reduces teeth grinding and clenching but also alleviates associated pain and protects teeth from further damage.

The procedure using botulinum toxin is quick, effective, and safe. The results are noticeable within a few days and last for several months, providing significant relief for patients.

Botulinum toxin, commonly known as Botox, is a neurotoxin produced by the Clostridium botulinum bacteria. It acts on the nerve endings within muscles by inhibiting the release of acetylcholine, a neurotransmitter responsible for transmitting impulses between nerves and muscles. As a result the treated muscles relax, leading to temporary weakening or complete cessation of contractions and therefore decreased muscle tension.

In bruxism therapy, botulinum toxin is injected into the masseter and temporal muscles, which are responsible for grinding and clenching teeth. By reducing the strength of their contraction, it is possible to significantly reduce the symptoms of this condition.

The substance injected into the muscle acts locally within the muscle itself. The first effects of the treatment are noticeable 24-48 hours after injection. Clinical muscle relaxation typically develops between day 4 and 10. After about two weeks, the maximum therapeutic effect is reached. After the initial Botox treatment, normal nerve transmission returns within 10 to 12 weeks after the injection. Therefore, the effect lasts about three months. With subsequent treatments, the effect can last up to six months.

The botulinum toxin treatment for bruxism is simple, quick, and minimally invasive. Here’s how the process works:

Step 1

Initial consultation

During the first visit, the dentist conducts a detailed interview, diagnosing the cause of bruxism, assessing the condition of the teeth, masseter muscles, and temporomandibular joints. Palpation of the facial and jaw muscles is often performed to determine the level of muscle tension.
Step 2

Preparation for the procedure

The practitioner identifies precise injection sites to ensure optimal results and maintain patient safety.
Step 3

Administering botulinum toxin

The doctor uses a fine needle to inject a small amount of botulinum toxin into selected areas, mainly the masseter muscles. Usually, several injections are made in each muscle, depending on the severity of bruxism. Injections are made at specific points responsible for muscle contractions to achieve the best therapeutic effect.
  • Duration of the procedure – The procedure typically lasts from 10 to 20 minutes, depending on the number of injections and the individual needs of the patient.
  • After the procedure – After the procedure, the patient can return to normal activities but should avoid intense massaging or pressing on the areas where the toxin was administered. Intense physical exercise should be generally avoided for a few days after the procedure.
  • Pain reduction – By relaxing the masseter and temporal muscles, pain in the jaw, head, and temporomandibular joints (TMJ) alleviates.
  • Reduced muscle tension – Botulinum toxin effectively reduces muscle tension, which decreases the frequency and intensity of teeth grinding and clenching.
  • Teeth protection – Less intense teeth grinding contributes to reducing wear and preventing microcracks in enamel, which can lead to cavities or tooth sensitivity.
  • Temporomandibular joint (TMJ) protection – Regular use of botulinum toxin can help protect the temporomandibular joints from overload, which could lead to pain and, in the long term, damage to the joints.
  • Night-time or daytime bruxism – Habitual teeth grinding and clenching, particularly if it causes pain in the face, jaw, head (e.g., migraines), or temporomandibular joint (TMJ) problems.
  • Tension-type headaches or migraines – Associated with excessive muscle tension in the face and head.
  • Excessive growth of the masseter muscles – Which may lead to jaw widening and changes in facial shape (e.g. a “square face”).
  • Teeth grinding during sleep – Which causes enamel damage and excessive tooth wear.
  • Allergy to botulinum toxin or any components of the product.
  • Neurological disorders – Such as myasthenia gravis, diseases related to muscle weakness, or conditions affecting the nervous system.
  • Skin infections – In areas where the toxin is to be injected.
  • Pregnancy and breastfeeding – There are insufficient studies on the safety of Botox during pregnancy and lactation, so it is not recommended during these periods.
  • Blood clotting disorders – Or the use of blood-thinning medications that may increase the risk of bleeding at the injection sites.
  • Facial expression disorders – Botox treatment may temporarily alter facial expressions, which may be undesirable for individuals with issues in this area.
