About 615 Smile Design Studio

Two dentists run 615 Smile Design Studio from Suite 110 on Belle Forest Circle, a quiet office pocket off Highway 70 South in Bellevue. Dr. Kevin Sivaneri handles the cosmetic and restorative side; Dr. Ashley Whetsell completed a general practice residency built around oral surgery, which is why extractions and surgical steps stay in-house rather than being referred across town. The studio describes its approach as cosmetic, conservative and metal-free, and says its restorative materials are fabricated in the United States. Alongside routine family care there is Invisalign, bonding, veneers, crowns and bridges, dentures and partials, periodontal treatment, TMJ therapy, custom mouthguards, and Botox and dermal filler work for the facial side of a smile case.

Minimal-prep veneers are where that conservative philosophy actually shows. A conventional veneer normally requires the front of the tooth to be reduced by roughly half a millimetre so the porcelain sits flush instead of bulking the tooth outward; a minimal-prep veneer is made thin enough that only light surface conditioning is needed, leaving most of the enamel intact. That matters because adhesive bonds to enamel far more reliably and durably than to the softer dentin beneath it, so the less you cut, the better the long-term seal. The trade-off is that minimal-prep only works when the underlying teeth are already close to the right shape and shade. Dark or tetracycline-stained teeth show through thin porcelain, crowded or rotated teeth generally need aligners first, and heavily worn or previously filled teeth may still call for conventional preparation. Any veneer, thin or otherwise, is permanent once enamel has been touched.

The practical details are straightforward. Belle Forest Circle is quick from Bellevue, West Meade and the Old Hickory Boulevard corridor, and a fair drive from downtown or the east side of the county. Hours run Monday through Thursday, eight in the morning to five in the evening, with Fridays closed — a full working day rather than a half one, which makes it easier to fit a long cosmetic or implant appointment into a single sitting instead of splitting it. New and existing patients call separate numbers. Emergencies are seen, sedation is available for people who need it, and the office is open about the comfort side of the visit: massage chairs, paraffin hand treatments, and your own music while you sit.

Drs. Kevin Sivaneri and Ashley Whetsell run a conservative, metal-free practice on Belle Forest Circle in Bellevue, covering minimal-prep veneers, bonding, Invisalign, crowns and bridges, implants, TMJ and periodontal treatment, alongside routine family care and sedation. Dr. Whetsell's oral surgery-based residency keeps extractions and surgical steps in the same office. Open Monday through Thursday, eight to five, with Fridays closed.

Frequently Asked Questions

What does this practice mean by metal-free dentistry?
It means restorations built from ceramic and composite rather than anything with a metal substructure, so no porcelain-fused-to-metal crowns with a dark margin appearing at the gumline as it recedes, and no amalgam fillings. All-ceramic work transmits light more like natural enamel, which is why it is favoured on front teeth. The practice states its restorative materials are made in the United States. Metal-free is not automatically stronger everywhere; the right choice depends on the tooth and your bite.
Do I have to go somewhere else for an extraction or an implant?
Usually not. Dr. Ashley Whetsell completed a general practice residency built around oral surgery, so extractions and surgical steps are handled at the Belle Forest Circle office instead of being referred out. Keeping the surgery and the restoration under one roof shortens the gap between removing a tooth and replacing it. Genuinely complex cases, such as deeply impacted teeth or significant medical complications, can still warrant a specialist, and a straight practice will tell you so.
Can I have Invisalign and veneers at the same office, and in what order?
Yes, and the order almost always matters. Moving crowded or rotated teeth into position with aligners first means the veneers that follow can be thinner and take less enamel, because the porcelain is not being asked to disguise a position problem as well as a colour one. Doing it the other way round tends to force thicker, more aggressive veneers. The trade-off is time, since aligner treatment adds months before the cosmetic phase starts.

I had a filling replaced today and felt it was worth leaving a review because Dr. Sivinari is exceptional at what he does. He takes a conservative approach and focuses on preserving as much natural tooth structure as possible. That level of care matters and provides real peace of mind knowing the work is being done the right way. No one enjoys having dental work done, but it makes a big difference when you’re treated by someone you trust. Dr. Sivinari is calm, precise, and intentional in his work. Dental procedures can be stressful, and his approach and attention to detail go a long way in making the experience straightforward and manageable. He is the only dentist I trust in the state of Tennessee. His staff and hygienists are equally impressive — professional, efficient, and consistently high quality. If you’re looking for a dentist who is conservative, detail-oriented, and takes real pride in his work, Dr. Sivinari is the best I’ve found.

They are very nice but they recommended a lot of very expensive work that I didn't need. They then did a procedure on my wife and the hygienist dropped an instrument on her face and never apologized. And I think something else happened during the procedure that made her want to go to another dentist. Anyway we went to a new (very respected) dentist who said we didn't need any of the dental work that was recommended. So maybe get a second opinion if they recommend a lot of expensive fixes like crowns etc.

I have never had such a pleasant experience during a dental appointment!! I just moved to the area and found 615 Smile on google, I called and talked to Paige a few separate times and her attitude on the phone made me excited about coming here. She was just as awesome in person and I was happy to see that the rest of the staff was just as welcoming and kind. My teeth also feel and look so much better after my cleaning. The dentist heard me out on my cosmetic concerns of my smile and built a plan out for me that I’m excited for. I would recommend them to absolutely everybody, 10/10

Your office can be summed up in one word "Amazing". I experienced amazing results yesterday. You guys were so nice and assuring right from the beginning. I actually feel that I have found my Dental Heros. I am scheduled to come back soon and i've never in my life been eager to enter a dentist's office, however, with the results I had yesterday, I'm so excited to experience more of the same. Maybe soon with you guy's help and expertise... I can also have a handsome smile. Thank you all in 615 Smile Design Studio Sincerely, Jeffery A. Casey
