Your smile is one of the first things people notice about you. If tooth discoloration or dullness has you hiding your grin, professional teeth whitening can help you regain confidence with whiter teeth that still look natural. At Smiley Dental Group, Dr. Holowicki, Dr. Moore, and Dr. Renshaw offer safe, effective whitening treatments for patients in Columbus, Dublin, and Hilliard, helping you achieve a brighter smile while protecting your oral health.
What Causes Tooth Discoloration?
Tooth stains can appear for many reasons, from daily habits to environmental factors. Common culprits include coffee, tea, red wine, and tobacco. Over time, these create surface stains that darken the enamel surface.
Intrinsic staining occurs deeper within the tooth structure and may result from aging, tooth decay, or certain medications. Unlike whitening toothpaste or store-bought whitening strips, professional whitening reaches both surface and internal discoloration for more consistent, dramatic results.

How Professional Teeth Whitening Works
At Smiley Dental Group, we use trusted whitening systems approved by the American Dental Association (ADA) to ensure safe, predictable results. The whitening procedure involves a bleaching gel containing hydrogen peroxide or carbamide peroxide, which breaks down discoloration on the surface of your teeth and brightens your tooth color.
You can choose from two types of treatment:
Professional vs. Over-the-Counter Whitening
While whitening strips and whitening toothpaste can lighten mild stains, they use lower concentrations of hydrogen peroxide and may not reach deeper discoloration. Professional treatments deliver better results and reduce risks like enamel erosion or uneven whitening often seen with counter products.
Our custom trays also prevent direct contact with gums, reducing side effects such as tooth sensitivity or irritation.
Safety and Sensitivity
If you’ve experienced sensitive teeth before, you can still safely whiten under professional supervision. Our team uses products with potassium nitrate and fluoride to reduce increased tooth sensitivity. We also apply gels only to your teeth, not your gums, to prevent discomfort.
Patients with gum disease, dental restorations, or enamel erosion can still achieve a brighter smile through customized cosmetic dentistry options designed for comfort and safety.
Benefits of Choosing Professional Whitening
- Brighter, natural-looking results in less time
- Safer treatments with reduced tissue damage risk
- Expert guidance to protect tooth enamel and oral hygiene
- Lasting results that can be maintained with good dental care
- A boost in confidence every time you smile
Results can last several months or longer depending on your oral hygiene and daily habits. Avoiding stain-causing foods, brushing with fluoride toothpaste, and scheduling regular dental visits will help maintain your whiter teeth.
Is Teeth Whitening Right for You?
Not everyone is a candidate for whitening. If you have tooth decay, gum disease, or unhealthy teeth, our dentists may recommend other cosmetic treatments such as dental veneers or bonding for your best result. During your consultation, we’ll assess your teeth and create a plan that protects your oral health while giving you the whitening effect you want.
