How Does Scleroderma Affect Your Teeth and Mouth?
At a Glance
Scleroderma increases the risk of dental issues by restricting mouth opening, causing severe dry mouth, and increasing acid reflux that erodes enamel. Using pediatric toothbrushes, frequent fluoride treatments, and sitting semi-upright during dental visits can help protect your teeth and airway.

When your rheumatologist refers you to a specialized dentist for systemic sclerosis (scleroderma), it is because the disease profoundly affects the mouth, teeth, and jaw in ways that a general dentist may not often see. Scleroderma causes structural (mechanical) changes, such as a tightening of the skin around the mouth and hands, and chemical changes, such as severe dry mouth and chronic acid reflux. A specialized dentist understands how these overlapping issues accelerate tooth decay and alter the underlying jawbone, and they can provide tailored strategies to protect your teeth. Because of these increased risks, your dentist will likely recommend more frequent check-ups and cleanings, often every 3 to 4 months rather than the standard 6 months.
The Mechanical Impacts: Small Mouth and Tight Hands
Scleroderma physically changes the skin and tissues of the face and hands, creating mechanical barriers to good oral hygiene:
- Microstomia (a restricted or narrowed mouth opening) is one of the most common challenges in systemic sclerosis [1][2]. The tightening of the facial skin makes opening wide painful or impossible, making it difficult for both you and your dentist to reach the back teeth [1][3].
- Sclerodactyly (thickening and tightening of the skin on the fingers) can make grasping a standard toothbrush handle difficult and painful [3][4].
To overcome these physical barriers, specialists often recommend using pediatric toothbrushes or electric toothbrushes with small heads to easily navigate a restricted mouth opening [5]. Adapting the toothbrush handle by sliding foam tubing or a tennis ball over it can help you maintain a strong grip despite hand stiffness [5]. Additionally, daily mouth-stretching exercises or physical therapy may be recommended to help maintain or improve your ability to open your mouth over time [6][3].
The Chemical Impacts: Dry Mouth and Acid Reflux
Scleroderma alters the chemical environment of your mouth, significantly increasing the risk of tooth decay and enamel erosion.
- Dry Mouth (Xerostomia): Many people with scleroderma also experience secondary Sjögren’s syndrome or severe dry mouth [7]. Saliva is naturally protective—it washes away food particles, neutralizes plaque acids, and repairs early tooth damage [7][8]. Without enough saliva, this protective buffering capacity is lost [7]. To manage day-to-day symptoms, your care team may suggest saliva substitutes, xylitol-based lozenges, or frequent water sipping.
- Severe Acid Reflux (GERD): Systemic sclerosis frequently causes gastrointestinal issues, leading to severe and chronic acid reflux [9][10]. When stomach acid regularly washes up into the mouth, it softens and erodes the hard enamel protecting the teeth [9]. A crucial tip: After a reflux episode, do not brush your teeth immediately, as brushing can scrub away the acid-softened enamel. Instead, rinse your mouth with water or a baking soda solution first.
The combination of a dry mouth and constant acid exposure requires proactive management [9][7]. To protect the enamel, a specialized dentist will often prescribe frequent fluoride treatments, such as a prescription neutral sodium fluoride toothpaste, which remineralizes the teeth and guards against decay without causing acidic irritation [11][12].
Unique Bone Changes and Misdiagnosis Risks
A specialized dentist is crucial because scleroderma causes unique changes to the jawbone that can easily be misdiagnosed by a provider unfamiliar with the disease.
Dental X-rays of patients with systemic sclerosis often show a widened periodontal ligament (PDL) space and areas where the jawbone appears to be eroding [13][14]. In a healthy person, a widened PDL is usually a sign of inflammatory periodontitis (severe gum disease) caused by plaque [15][16]. However, in scleroderma, this widening is a direct result of the disease’s fibrotic (scarring) process, rather than just inflammation or poor hygiene [15][17].
While people with scleroderma can still develop standard gum disease that needs treatment, a specialist is trained to distinguish between routine periodontitis and scleroderma-related changes. If a general dentist misinterprets these X-rays, they might recommend painful, expensive, and unnecessary deep cleaning procedures that will not resolve the underlying systemic issue [18][17].
Adapting the Dental Visit for Scleroderma
Seeing a specialized dentist also ensures your safety and comfort during routine cleanings and exams. Because severe GERD and esophageal motility issues are common in scleroderma, lying completely flat in a dental chair increases the risk of stomach fluids reaching the throat or lungs [19][20]. Furthermore, patients with lung involvement, such as pulmonary fibrosis, may experience breathing difficulties when lying flat [21][22].
To prevent these complications, a specialized provider will keep the dental chair in a semi-upright position to protect your airway and maintain comfortable breathing [19][21]. They will also use smaller mirrors and instruments, and potentially specialized mouth props, to minimize the strain on your lips and jaw caused by microstomia [1][23].
