SANACIÓN AVANZADA COMO NO EXISTE EN OTRO LUGAR DE RI ✨

En Bio Dental utilizamos PRF (Fibrina Rica en Plaquetas) en cirugía dental para llevar la sanación del paciente al más alto nivel.

El PRF se obtiene de la propia sangre del paciente y está cargado de factores de crecimiento naturales que ayudan a:
✔️ Acelerar el proceso de cicatrización
✔️ Disminuir inflamación, dolor y sangrado postoperatorio
✔️ Reducir significativamente el riesgo de infección
✔️ Mejorar la regeneración de tejido y hueso

Al ser un tratamiento 100% natural y autólogo, no hay riesgo de rechazo, reacciones adversas ni efectos secundarios—no se utilizan químicos ni materiales sintéticos.

Este enfoque regenerativo permite que el cuerpo sane más rápido, de forma más limpia y predecible, logrando mejores resultados a largo plazo.

🌿 Esto es odontología biológica en su máxima expresión.

Snoring doesn’t just steal sleep — it steals connection.
Separate bedrooms. Interrupted rest. Frustration night after night.

CPAP machines often add another barrier — masks, noise, discomfort — and many partners still struggle with compliance and intimacy.

NightLase® at Bio Dental is different.
No machines. No masks. No bedtime battles.
Just gentle, non-invasive treatment that helps improve airflow and quiet snoring at its source.

Better sleep brings couples back together.
Rested mornings. Shared beds. Stronger relationships.

At Bio Dental, we choose NightLase® because sleep should heal your health and your marriage. 💙😴 Call today....we can help 401-232-7777.

Snoring treatment shouldn’t be uncomfortable.

CPAP machines rely on nightly compliance—masks, hoses, noise, and inconvenience. When they’re not used consistently, results disappear.

NightLase® at Bio Dental works without machines or masks.
✔ Non-invasive
✔ No appliances to wear at night
✔ Comfortable, fast treatments
✔ Long-lasting improvement
✔ Better sleep for you and your partner

We choose NightLase® because it treats snoring at the source—by improving airway stability—while fitting real life.

At Bio Dental, better sleep starts with a better solution. 😴✨

Snoring is more than noise.
It affects sleep quality, overall health, and can strain relationships and marriages. Poor sleep impacts energy, focus, mood, and long-term wellness.

At Bio Dental, we treat the cause—not just the sound.
We use NightLase®, a gentle, non-invasive laser therapy that helps tighten airway tissues, improve breathing, and reduce snoring—no devices, no surgery.

Better sleep. Better health. Better relationships.
Because restful sleep changes everything. 💙

Diabetes & Dental Health: A Biological Perspective

In biological dentistry, we understand that the mouth is connected to the entire body—and diabetes makes that connection even more important.

Elevated blood sugar fuels inflammation, infection, and poor healing, especially in the gums and jawbone. This increases the risk of:

Chronic gum disease, Bone loss around teeth, Hidden oral infections and Delayed healing after dental procedures.
At Bio Dental, we take a holistic approach by: Identifying and reducing oral inflammation, Supporting the body’s natural healing response, Using biocompatible materials and Collaborating with medical providers when needed

By addressing the root causes—not just the teeth—we help patients with diabetes protect their oral health and support their overall wellness.

Whole-body care starts in the mouth.

Sometimes, brushing your teeth isn’t enough to remove stains caused by the drinks you consume.
