Dental Health Is Linked to Overall Wellness—Here’s How an Expert Suggests You Level Up Your Hygiene

My aunt was my dental hygienist when I was growing up, so I'd like to think I have a leg up with dental hygiene. I knew to floss and brush twice a day—with a timer to ensure I brushed long enough—and to use an electric toothbrush to help combat my tooth sensitivities. My X-rays were up to date, I never missed my twice-yearly cleanings, and I didn't even mind the fluoride treatments my aunt insisted on.

While I knew it was important to take care of my teeth and gums to avoid cavities, I'm a little embarrassed to admit that it wasn't until I spoke to Dr Daniel Rubinshtein, D.D.S that I learned the true impact of dental hygiene on overall health and well-being.

Dr. Rubinshtein, a cosmetic dentist based in New York City and the founder of Aesthetic & Laser Dentistry of New York, focuses on advanced cosmetic and restorative dentistry, including smile makeovers, porcelain veneers, implants, and full-mouth rehabilitation. As someone who can't even listen to my husband chew—never mind stare into people's mouths all day—I was surprised to learn how passionate Dr. Rubinshtein is about his work.

"What I love most about cosmetic dentistry is that it sits at the intersection of health, artistry, and human connection," he tells me. "A beautiful smile can absolutely change someone aesthetically, but more importantly, it can change how they carry themselves, communicate, and experience confidence in everyday life."

The Impact of Oral Health on Overall Health

In today's health-conscious world, where we're always looking to optimize our sleep, fitness, and diet, it's surprising to learn that dental hygiene is still viewed as mostly an aesthetic choice.

"Oral health is deeply connected to overall health, and I think many people still underestimate that connection," says Dr. Rubinshtein. "The mouth is not separate from the body. Inflammation, infection, and bacteria in the mouth can impact overall wellness in significant ways."

He outlines the strong links between gum disease and systemic conditions such as chronic inflammation, diabetes, cardiovascular disease, and even pregnancy complications. He also mentions that chronic dental discomfort or sensitivity can significantly affect stress levels, sleep, nutrition, and quality of life.

"I always tell patients that healthy teeth and gums are not just about aesthetics. A beautiful smile is great, but the real foundation is maintaining a healthy oral environment long term," he says.

In fact, Dr. Rubinshtein wishes people would stop chasing ultra-white teeth at the expense of their oral health. TikTok trends for DIY dental brightening hacks, like using baking soda, lemon juice, charcoal, and other abrasive ingredients can increase sensitivity and potentially damage teeth.

"Simple habits like using the right toothpaste, brushing gently, limiting acidic exposure, and staying proactive with dental care can make a major difference long term."

Dr. Rubinshtein's Expert-Approved Routine

My obvious follow-up question was about Dr. Rubinshtein's recommended routine. "The most effective routines are usually the most consistent and realistic ones," he says. "I recommend brushing [for two minutes] twice daily with toothpaste, flossing every day, staying hydrated, and keeping up with regular professional cleanings and exams. I also encourage patients to pay attention to habits throughout the day with things like sipping acidic drinks constantly, chewing ice, aggressive brushing, or overusing whitening products that quietly damage enamel over time."

He also cautions against brushing too hard because that can wear down enamel, cause gum recession, and increase sensitivity over time. He recommends using a soft-bristled toothbrush and applying gentle pressure.

Why Sensodyne?

As for his toothpaste recommendation, Dr. Rubinshtein says he's a big believer in products that support long-term oral health and sensitivity prevention instead of quick fixes. He suggests Sensodyne's Clinical Repair line, which was also recommended to me by my aunt when I complained of sensitivity.

He assures me sensitivity is really common today due to the popularity of teeth-whitening products, acidic diets, and aggressive oral-care trends.

"What I appreciate about Sensodyne products, particularly the Clinical Repair line, is that they're designed to help address sensitivity while also supporting enamel strength and long-term oral health. Patients want products that work but also feel easy to incorporate into everyday routines, and I've found that consistency with the right products can make a noticeable difference."

Despite the fact that I did not fully grasp how important dental health was for overall health, I am happy to report I've been using Sensodyne for years. The Clinical Repair Whiten & Shine Toothpaste is a personal favorite because I wanted something that continued to whiten my teeth (sorry, Dr. R) without exacerbating my tooth pain. The formula activates right when you start to brush your teeth to help form a protective layer over exposed and sensitive areas of your teeth. What I've loved most is that the protective layer strengthens with each use—at this point, I barely suffer from sensitivity.

To close, I asked Dr. Rubinshtein if he had any recommendations heading into summer—a season when we tend to indulge a bit more. His biggest advice?

"Stay hydrated with water, especially after consuming sports drinks, cocktails, lemonade, or soda. Water helps neutralize acids to help protect the teeth from potential damage."
