See How!

Here are some tips to help reduce dental fear and anxiety:

Talk to the dentist.

The dentist is not a mind reader. Though it can be hard to talk about irrational fears with a stranger, the dentist can take extra precautions during visits if fears and anxiety are communicated.

Choose your favorite music.

Music acts as a relaxant and drowns out any fear-producing noises. Listening to calming music throughout the appointment will help to reduce anxiety.

Agree on a signal.

Many people are afraid that the dentist will not know they are in significant pain during the appointment, and will continue the procedure regardless. The best way to solve this problem is to agree on a “stop” hand signal with the dentist. Both parties can easily understand signals like raising the hand or tapping on the chair.

Spray the throat.

Throat sprays (for example, Vicks® Chloraseptic® Throat Spray) can control the gag reflex. Two or three sprays will usually keep the reflex under control for about an hour.

Ask for a mirror.

Not being able to see what is happening can increase anxiety and make the imagination run wild. Watching the procedure can help keep reality at the forefront of the mind.


If there is no other way to cope, sedation offers an excellent option for many people. There are several types of sedation, but the general premise behind them is the same: the patient regains their faculties after treatment is complete.

Ask about alternatives.

Advances in technology mean that dental microsurgery is now an option. Lasers can be used to prepare teeth for fillings, whiten teeth and remove staining. Discuss all the options with the dentist and decide on one that is effective and produces minimal anxiety.

If you have questions or concerns about how the dentist can help you overcome anxiety and fear, please contact the office.
