Light-Based Therapies in Modern Dentistry

While there are trillions of individual nerve fibers in your body, only about 86 are considered major nerves, arranged in 43 pairs. Twelve of those are cranial nerves, and one of those has been drawing a whole lot of attention lately – at least in medical and wellness research.

That would be the vagus nerve.

Often described as the body’s communication superhighway, the vagus runs from the brainstem through the neck and into the chest and abdomen. It connects the brain with major organs involved in digestion, heart function, immune response, and stress regulation.

But one thing about it that’s interested researchers in particular is the role of the vagus in helping the body shift between two key states of the nervous system: fight-or-flight and rest-and-restore; alarm and calm, with the calm mode supporting healing, digestion, and recovery.

Many of us, though, habitually spend too much time in the alarm mode, courtesy of chronic stress and anxiety. The imbalance means less time to recover, which can sometimes wind up making the stress worse.

This raises the possibility of how we might work with the vagus nerve to support the body’s natural ability to regulate stress, inflammation, and recovery – therapies that work with the body’s existing biology.

One of the newest is a procedure called VagusLase, which uses carefully controlled laser energy to stimulate tissues in the soft palate and surrounding areas that lie along pathways connected with the vagus nerve. The goal is to gently encourage activity within these tissues and support the body’s own regulatory systems.

Yes, parts of the nerve pathway run right through areas that we work with every day here in our biological dental office: the throat, palate, tongue, and adjacent oral tissues. That’s what makes this procedure such a great fit for us. It’s also a great fit for our patients, being so gentle, comfortable, and non-invasive – no incisions or injections involved.

For a VagusLase session, you relax in one of our dental chairs while we use our Fotona LightWalker to apply a precise wavelength of laser energy to specific areas of your soft palate and throat. Most patients describe the sensation as a gentle warmth. The full treatment lasts just a few minutes and doesn’t require anesthetic, so there’s usually no downtime. You can get on with the rest of your day immediately afterward.

Here’s what one patient had to say after her first VagusLase session:

Of course, this is hardly the only procedure we can do with our Fotona laser – an advanced system that combines two laser wavelengths into a single device. One – Er:YAG – interacts well with hard tissues, such as enamel and bone, while the other – Nd:YAG – is designed to work with soft tissues, including gums, mucosa, and the structures of the throat.

This design means we can use the LightWalker for many dental procedures lasers are already known for, from periodontal therapy to soft tissue surgical procedures to certain treatments involving teeth and bone. But it also lets us work with tissues in a very different way, using carefully controlled pulses of light to stimulate biological responses within living tissue. Depending on how the laser is applied, this can encourage circulation, collagen production, and tissue remodeling.

For instance, some applications focus on improving how the muscles and connective tissues of the mouth work together. OraLase is one that can help relax areas of tension within the body’s fascial network. By stimulating cellular activity and circulation, the procedure encourages tissues to release restriction and move more naturally. This makes it especially helpful in cases where limited tongue movement is being caused by tension in the fascia rather than a structural tongue-tie. When fascial tension restricts normal movement, the tongue may appear tied even though the underlying structures are normal.

The same principles can also be applied to very young patients. BabyLase is suited for infants and toddlers, where concerns such as tongue and lip ties, feeding difficulty, and early airway development can affect how a child grows and functions. By working gently with the tissues involved in oral movement, the therapy offers good support during a critical stage of development.

Other laser applications focus on structures deeper in the throat and airway. NightLase is designed to address snoring and mild sleep-disordered breathing by stimulating collagen production in tissues at the back of the throat. As those tissues become firmer and more supportive, the airway can remain more open during sleep.

Our LightWalker can even be used to support facial tissues. SmoothLase, for instance, stimulates collagen production around the mouth, helping improve tone and elasticity without injections or surgery. LipLase does the same to give fullness to the lips naturally, no fillers required.

And who better than a dentist to do such procedures, being trained in and deeply familiar with the anatomy of the lips, cheeks, jaw, and surrounding musculature? Facial aesthetics also can complement many dental procedures, particularly those that improve the look and function of the smile, such as O2dontics or cosmetic treatments.

And all this simply by stimulating the body’s own systems in ways that weren’t possible even a decade ago.
