How Charcot-Marie-Tooth Disease Affects Your Oral Health

Charcot-Marie-Tooth Disease (CMT) is a group of inherited neurological disorders that affect the peripheral nerves, leading to progressive muscle weakness and sensory loss. Though CMT primarily impacts mobility and motor functions, it can also pose unique challenges for maintaining good oral health. The condition affects various aspects of a person’s life, including chewing, swallowing, and speaking.

In this article, we will explore the connection between Charcot-Marie-Tooth Disease and oral health, discuss common dental problems associated with the disease, and offer practical solutions to help manage these issues effectively.

What is Charcot-Marie-Tooth Disease (CMT)?

Charcot-Marie-Tooth Disease is the most common inherited neurological disorder, affecting approximately 1 in 2,500 people worldwide. The disease primarily affects the peripheral nervous system, which controls muscles and relays sensory information to the brain. CMT causes damage to the peripheral nerves, resulting in symptoms such as:

• Muscle weakness: Especially in the feet, legs, hands, and forearms.
• Sensory loss: Decreased sensation in the limbs, including numbness and tingling.
• Muscle atrophy: Progressive wasting of muscle tissue.
• Impaired motor skills: Difficulty with coordination, walking, and fine motor tasks such as writing or buttoning a shirt.

There are several types of Charcot-Marie-Tooth Disease, which vary in terms of severity and progression. Symptoms usually begin in adolescence or early adulthood, but they can also present in childhood or later in life.

The Connection Between Charcot-Marie-Tooth Disease and Oral Health

While Charcot-Marie-Tooth Disease is primarily recognized for its impact on movement and sensation, its effects on oral health are often overlooked. Due to the weakening of muscles that control oral functions, individuals with CMT face a variety of dental challenges.

Below, we explore how this disease impacts different aspects of dental care and what can be done to address these issues.

1. Difficulty with Oral Motor Skills

One of the most significant impacts of Charcot-Marie-Tooth Disease on oral health is the difficulty in controlling the muscles used for chewing, swallowing, and speaking. As CMT weakens the muscles in the face and jaw, individuals may find it harder to perform these essential oral functions. This can lead to several issues:

• Chewing difficulties: Weakened jaw muscles make it harder to chew food properly, which can result in difficulty breaking down food and a risk of choking.
• Swallowing issues: Reduced muscle control may cause problems with swallowing, leading to the aspiration of food or liquids into the airways, which can cause coughing or even choking.
• Speech problems: Individuals with CMT may experience slurred speech or difficulty pronouncing certain words due to impaired control of the tongue and facial muscles.

Maintaining oral motor skills is essential not only for eating and speaking but also for ensuring that oral hygiene routines are carried out effectively.

2. Bruxism (Teeth Grinding)

Another common dental issue faced by individuals with Charcot-Marie-Tooth Disease is bruxism, or teeth grinding. People with CMT may grind or clench their teeth, especially at night, due to stress or muscle spasms. Bruxism can lead to a number of dental problems, including:

• Tooth wear: Over time, grinding can wear down the enamel, leaving teeth more vulnerable to cavities and sensitivity.
• Jaw pain: The pressure from grinding can cause pain in the temporomandibular joint (TMJ), leading to headaches, facial pain, and jaw discomfort.
• Tooth fractures: Constant grinding can also cause cracks or fractures in teeth, making them more susceptible to breakage.

For individuals with CMT, bruxism may be exacerbated by muscle weakness in the jaw, making it more difficult to manage without professional intervention.

3. Gum Disease (Periodontal Disease)

People with Charcot-Marie-Tooth Disease may be more susceptible to gum disease due to difficulty with maintaining oral hygiene. Weak hand and finger muscles can make it harder to brush and floss properly, leading to an increased risk of plaque buildup on the teeth and gums. This can result in gingivitis (early-stage gum disease), which can progress to periodontitis (severe gum disease) if left untreated.

Gum disease can cause:

• Swollen, bleeding gums: Early signs of gum disease include redness and inflammation of the gums, which may bleed when brushing or flossing.
• Tooth loss: As gum disease progresses, it can weaken the structures supporting the teeth, leading to tooth mobility and eventual tooth loss.

Regular dental checkups are essential for people with Charcot-Marie-Tooth Disease to monitor and manage gum health.

4. Dry Mouth (Xerostomia)

Dry mouth, or xerostomia, is another common issue for individuals with Charcot-Marie-Tooth Disease. It can occur for several reasons:

• Reduced saliva production: CMT can affect the salivary glands, leading to decreased saliva flow.
• Medications: Some medications used to manage CMT symptoms may contribute to dry mouth as a side effect.

Saliva plays a crucial role in maintaining oral health by washing away food particles, neutralizing acids, and protecting the teeth from decay. Without enough saliva, individuals with dry mouth are more prone to tooth decay, gum disease, and difficulty swallowing or speaking.

5. Bite and Alignment Issues

Due to the muscle weakness caused by Charcot-Marie-Tooth Disease, individuals may develop bite problems over time. The weakening of the muscles that control the jaw can cause misalignment, which can result in:

• Malocclusion: Misalignment of the teeth, where the upper and lower teeth do not meet properly, can cause difficulty chewing and increased wear on certain teeth.
• Jaw pain: Misalignment may contribute to TMJ disorders, which can cause jaw pain, headaches, and discomfort when moving the jaw.

Bite issues can further exacerbate problems with chewing, swallowing, and speaking, making it essential to address these concerns early.

Managing Oral Health with Charcot-Marie-Tooth Disease

While Charcot-Marie-Tooth Disease presents unique challenges for oral health, there are several ways to manage these issues effectively. Here are some tips for maintaining good dental care with CMT:

1. Create an Adapted Oral Hygiene Routine

Maintaining a consistent oral hygiene routine is essential, but individuals with Charcot-Marie-Tooth Disease may need to adapt their approach to accommodate muscle weakness and difficulty with fine motor control. Here are some strategies:

• Use electric toothbrushes: Electric toothbrushes with larger handles can be easier to maneuver, making it simpler to brush thoroughly.
• Use flossing aids: Flossing can be challenging with weak fingers, so using flossing tools or interdental brushes can make the process easier.
• Consider professional cleanings: Regular visits to the dentist for professional cleanings will help remove plaque buildup and prevent gum disease.

2. Wear a Night Guard for Bruxism

If bruxism is an issue, a custom night guard can help protect the teeth from the damaging effects of grinding. Night guards are designed to fit over the teeth and cushion them against the pressure of grinding, preventing wear and tooth fractures.

3. Manage Dry Mouth

If dry mouth is a concern, there are several solutions to help alleviate discomfort:

• Drink plenty of water: Staying hydrated throughout the day can help stimulate saliva production.
• Use saliva substitutes: Over-the-counter saliva substitutes or mouthwashes can help keep the mouth moist.
• Chew sugar-free gum: Chewing gum can stimulate saliva production and relieve dry mouth.

4. Address Bite and Alignment Issues

For individuals with bite or alignment issues caused by Charcot-Marie-Tooth Disease, orthodontic treatment may be recommended. Braces or other orthodontic appliances can help correct bite issues and alleviate jaw discomfort. In some cases, dental crowns or bridges may be necessary to restore the function and appearance of the teeth.

5. Regular Dental Checkups

Frequent dental visits are crucial for individuals with Charcot-Marie-Tooth Disease. Regular checkups allow the dentist to monitor oral health, detect issues early, and provide personalized recommendations for managing dental challenges. Your dentist can help identify signs of gum disease, tooth decay, or other issues before they become more serious.

Conclusion

Charcot-Marie-Tooth Disease can present significant challenges for maintaining oral health, but with the right strategies and professional care, individuals with CMT can protect their teeth and gums. By adapting oral hygiene routines, managing bruxism, addressing dry mouth, and seeking timely orthodontic care, people with Charcot-Marie-Tooth Disease can maintain a healthy smile despite the condition’s effects.
