Our story, since 1991

Dr. William Neff grew up with a father who was a dentist, and always wanted a family practice of his own. He has cared for Murrieta families since 1991, and some patients he first saw at three now bring in three-year-olds of their own.

Today he is joined by Dr. Meerweis Stanisai, and the practice is still family-owned.

He is always involved himself in the cleaning process...not just dropping in for a 2 second exam and X-ray viewing like some dentists do. I have never had to wait well beyond my scheduled appointment time to be seen. Jenna P.Yelp, June 2019

What people ask about most.

Porcelain Veneers

Your natural teeth stay largely intact, with only a minimal amount altered to fit the veneer. A quick fix for shape, size or colour, gaps and superficial stains.

Lumineers

Specialty porcelain veneers, digitally designed to be ultra-thin, about the size of a contact lens. Dr. Neff is a certified Lumineers dentist.

Teeth Whitening

Store-bought trays rarely fit, and leaking gel irritates the gums. We fit the trays, monitor your progress and treat any sensitivity along the way.

Wisdom Teeth

Early evaluation in the mid-teenage years is recommended. X-rays show whether they are a problem now or will be later, and extractions are done here.

Kid-friendly dentist

We treat your children as we would our own.

Since 1991, Murrieta parents have trusted Dr. Neff with their children’s teeth. The aim is simple: a positive dental experience for every toddler, child and teenager, and fewer cavities.

01

The first visit

As soon as you can brush your child's teeth without a fuss, on average between two and three years old. Sooner if you notice a dark spot or stain that will not go.

02

Parents welcome

You are welcome in the room. We check your child's dental development, and habits like thumb, finger and pacifier sucking, before they affect growth.

03

Sealants & fluoride

Sealants on permanent molars and bicuspids as they erupt, and routine fluoride treatments to harden the weakened spots where cavities begin.

04

Pain-free fillings

Most children's cavities are restored with tooth-coloured fillings under local anesthesia. Laughing gas (nitrous oxide) is available to ease anxiety.

Common questions

Are you accepting new patients?

Yes. We are currently accepting new patients, of every age. To make your first visit smooth, complete the New Patient Packet ahead of time and email it to gtriangledds@gmail.com, and please arrive 15 minutes before your appointment.

Do you take my insurance?

We work with most dental insurance plans, including most PPOs. We accept cash, checks, Visa, MasterCard, Discover, American Express and CareCredit, and payment is expected at the time services are performed.

I get anxious at the dentist. Can you help?

We believe dental care should be gentle, non-stressful and anxiety-free. Blankets, bottled water and televisions are always available, and if you have extreme anxiety or are uncomfortable with a procedure or exam, nitrous oxide is recommended.

When should my child first see a dentist?

As soon as you are able to brush your child's teeth without a fuss, on average between two and three years old. If you notice a problem, such as a dark spot or stain that will not come off, please schedule an appointment sooner.

Do wisdom teeth always need to come out?

No. Early evaluation in the mid-teenage years is recommended, and dental x-rays show whether they are a present or future problem. When a tooth does need to come out, it is extracted gently in-house with local anesthesia, and nitrous oxide is available.
