State-of-the-art dentistry for everyday smiles
Teeth Whitening
Michael M. Bohn DDS
Teeth Whitening
There’s a noticeable difference between teeth that have been whitened professionally and teeth that have been treated with over-the-counter products, and it comes down to more than just how bright they get. Teeth whitening in Fresno at our practice uses professional-grade materials applied with clinical precision, which means more consistent results, less sensitivity, and a process that’s tailored to what your teeth can actually handle. If you’ve tried whitening strips or trays from the drugstore and been underwhelmed, this is a different experience.
Our Mission:
To deliver state-of-the-art, relationship-based dentistry that helps every patient feel comfortable, cared for, and confident in their smile.
Our Vision:
To set the standard for personalized, comprehensive dental care in Fresno — where exceptional outcomes and a welcoming experience go hand in hand.

Why Professional Whitening Works Better
Store-bought whitening products have to be formulated conservatively because they’re used without any professional oversight. The concentrations are lower, the trays are generic, and there’s no pre-evaluation to determine whether whitening is even the right approach for your specific type of staining.
Professional whitening starts with an exam. Dr. Michael M. Bohn evaluates your teeth and gums before recommending treatment, which is important for several reasons. Not all discoloration responds to whitening. Stains caused by certain medications, fluorosis, or internal tooth changes require different approaches. Knowing what you’re working with upfront prevents you from investing in a treatment that won’t address the actual cause of the discoloration.
It also helps identify any existing restorations that could affect your results. Crowns, veneers, and bonding don’t whiten the way natural enamel does, so we factor those in when setting expectations and planning treatment.
Teeth Whitening in Fresno: Your Options
We offer both in-office and take-home whitening, and the right choice depends on your timeline, sensitivity, and the level of change you’re looking for.
In-Office Whitening
In-office treatment produces the most immediate results. The whitening gel is applied directly to your teeth under controlled conditions, and your gums are protected throughout the process. Most patients see a significant difference after a single session. It’s a good option if you have an event coming up or simply want results without waiting.
Take-Home Whitening Trays
Custom trays are made from impressions of your teeth, which means the fit is precise and the gel stays where it’s supposed to rather than spreading onto the gums. You wear them for a set amount of time each day for a couple of weeks. The results are comparable to in-office treatment, just spread out over a longer period. Many patients prefer this because they can whiten on their own schedule and use the trays for touch-ups later.
What to Expect During Treatment
In-office whitening is straightforward. We start by protecting your gum tissue, then apply the professional whitening gel to your teeth. You relax while the gel works, and we monitor the process throughout. When the session is complete, we review the results with you and talk through how to maintain them.
Sensitivity during or after whitening is possible, though our professional products and techniques are designed to minimize it. If you have a history of sensitive teeth, let us know before treatment begins. We can adjust the approach or recommend a desensitization protocol to make the process more comfortable.
How Long Do Results Last
Whitening results aren’t permanent, but they’re also not as short-lived as some people expect. Most patients see their results last from 6 months to 2 years, depending on diet and habits. Coffee, tea, red wine, and tobacco are the most common contributors to re-staining. Brushing after consuming staining foods and drinks, and keeping up with regular cleanings, goes a long way toward extending how long your results hold.
Touch-up treatments, whether with your custom trays or a periodic in-office session, are an easy way to maintain brightness over time without starting from scratch.
Frequently Asked Questions About Teeth Whitening in Fresno
Will whitening work on my crowns or veneers?
Whitening agents only affect natural tooth enamel, not restorative materials. If you have crowns, veneers, or bonding on visible teeth, we’ll talk through how that affects your expected results and whether any additional steps make sense.
How much sensitivity should I expect?
Sensitivity varies from person to person. Some patients feel nothing; others notice temporary sensitivity to cold during or shortly after treatment. It typically resolves within a day or two. We can recommend products that help manage it if needed.
Can I whiten if I have cavities or gum disease?
Not until those issues are treated. Whitening on compromised teeth or inflamed gum tissue can cause significant discomfort and uneven results. Getting your oral health in good shape first is always the right sequence.
How soon after whitening can I eat and drink normally?
We recommend avoiding dark-colored foods and beverages for at least 48 hours after treatment, as the enamel is more porous immediately after whitening and more susceptible to re-staining during that window.
Is professional whitening safe?
Yes, when used as directed and applied by a dental professional. The evaluation beforehand ensures whitening is appropriate for your teeth, and the controlled application reduces the risk of gum irritation or uneven results.
