If you or your partner is experiencing persistent snoring or restless nights, it may be more than just a minor inconvenience; it could be a sign of sleep apnea.

At Mark L Harris, DMD, we offer dental-based solutions designed to support healthier, more restorative sleep. Our team conducts a thorough evaluation to understand your airway, sleep patterns, and overall needs, then recommends a comfortable, custom-fitted oral appliance that helps keep your airway open throughout the night. This non-invasive approach can reduce snoring, improve breathing, and promote deeper, more consistent sleep.

Take the first step toward better rest and improved well-being. Schedule your sleep consultation today.

Does your jaw click, ache near your temples or ears, or leave tension radiating into your neck and shoulders?

At Mark L Harris, DMD, evaluating the temporomandibular joint (TMJ) is an important part of every routine dental exam. If we notice signs of TMJ dysfunction (TMD), our goal is to stop further damage, protect your teeth, and correct underlying bite issues before they worsen. Treatment is always personalized and may include a comfortable bite appliance, stress management techniques, and practical daily adjustments, such as avoiding gum, choosing softer foods, taking smaller bites, and alternating chewing sides.

Don’t let jaw pain take over your day. Schedule your TMJ evaluation today and start finding real relief.

Struggling with a toothache that just won’t let up?

At Mark L Harris, DMD, root canal therapy is nothing like the intimidating procedures of the past. Thanks to advanced technology and gentle anesthetics, many of our patients find the treatment so comfortable they nearly fall asleep—and in most cases, it’s completed in just one visit. The process is straightforward: we carefully clean and disinfect the canal, fill it with a safe, biologically inert material, and seal it to protect against future infection. Afterward, a little soreness is normal, but most patients manage it easily with over-the-counter relief and routine oral care.

Don’t put off saving your natural tooth. Contact us today and experience root canal therapy redefined.
