Overview
What Is Specialty Dental Care at Seacoast Prosthodontics?
Specialty dental care looks at more than one tooth at a time. At Seacoast Prosthodontics, we look at your whole mouth, including your bite, jaw joints, and the muscles that control chewing and sleep. Dr. Randi's background, dental school at Columbia University, a General Practice Residency at the Brooklyn VA, and a Prosthodontics Residency at the Manhattan VA, gives him a deep understanding of how these systems connect. Instead of treating a single symptom, we look for the root cause so treatment holds up over time.
Why Here Benefits of Specialist-Led Care for Jaw, Bite, and Sleep Concerns
Working with a prosthodontist for these concerns means your care is planned around how your whole mouth functions, not just one complaint. We use digital impressions and 3D CT scanning to get a precise picture of your bite and jaw joints before recommending treatment. This level of detail helps us build appliances and treatment plans that fit well and hold up over time. For patients who feel anxious about dental visits, we also offer sedation dentistry to help you stay comfortable during treatment.
Options Our Specialty Services
Each of the services below addresses a different but related concern. Many patients deal with more than one of these issues at once, since jaw pain, grinding, and sleep problems often overlap.

TMJ Therapy
Jaw pain, clicking, or trouble opening your mouth fully can point to a problem with your temporomandibular joint, or TMJ. Our TMJ therapy starts with a careful exam of your bite and jaw movement, then builds a treatment plan designed to ease pain and restore comfortable function.

Sleep Apnea Treatment
Snoring and interrupted sleep are not just annoying, they can affect your health. Our sleep apnea treatment includes custom oral appliances designed to keep your airway open at night, offering an alternative for patients who struggle with a CPAP machine.

Bruxism Treatment
Grinding or clenching your teeth, often called bruxism, can wear down enamel and strain your jaw over time. Our bruxism treatment may include a custom nightguard or NTI device built to protect your teeth and ease muscle tension.

Dr. Randi's prosthodontic training means he evaluates jaw, bite, and sleep concerns as connected parts of one system, not isolated problems. Our team also takes time to explain insurance coverage over the phone, so you understand your options before committing to treatment.
Good To Know
Frequently Asked Questions
How do I know if I need TMJ treatment?
Common signs include jaw pain, clicking or popping sounds, headaches, or trouble opening your mouth wide. If these symptoms last more than a few weeks or affect your daily life, it is worth scheduling an exam so we can check your bite and jaw joint function.
What does sleep apnea treatment involve at a dental practice?
Treatment usually starts with a conversation about your symptoms and sleep history, often alongside input from your physician. If an oral appliance is a good fit, we take precise digital impressions to design a custom device that helps keep your airway open at night.
Is bruxism treatment covered by insurance?
Coverage for bruxism treatment, including nightguards, varies by plan. Our team can review your specific benefits with you over the phone so you know what to expect before moving forward with treatment.
