Janak Tull DMD

We’re so excited to welcome our new hygienist Linda to the team at DenTull!
Enamel is composed of a compound known as Hydroxyapatite. Apatite is a rare earth mineral. If you have ever seen your teeth under a black light you may have noticed that they glow. Teeth fluoresce under black lights because of this mineral compound that composes enamel. It also happens to be a crystalline structure. This means that you have a mouth full of crystals that you use express all of your emotions and communicate with the world. Take care of your teeth, because eventually your teeth will take care of you.
What matters to you?
Hi I’m Dr. Janak and your teeth are crystals. Your enamel is made out of a crystalline structure known as #hydroxyapatite

Form over function?


Though dentistry is certainly a form of art - functionality is paramount. 

The perfect smile does not exist and the perfect teeth do not exist either. 

Everyone’s teeth and smiles are unique to them. 

The right shape, the right shade, and the right position for you - are what’s best for you. 

You are what you eat and you are who you breath. 

Ever leave your friends tooth in bleach too long? It might make it look more interesting when you turn it into an earring for them.
What kind of car does your dentist drive? What about your acupuncturist?

Client Testimonials

Least painful dental experiences of my life.

I've been to excellent doctors, but none have ever conveyed a love for their craft to the extent that Dr. Tull does.

Dr. Lekha Tull has been my dentist for the over 30 years.

I have had nothing but good experiences at this office. Her son Dr. Janak Tull has joined the practice, he is just as kind and competent.

Dr. Tull (Janak) is awesome!

As most do, I dread going to the dentist. After a suggestion from a friend to try DenTull, my idea of a dental visit has completely changed.

We look forward to seeing Dr. Janak

Dr. Janak took the to time needed rather than the the easy way out. Both Dr Tull’s are amazing professional and take the time and care to keep their patients informed and safe.
