Most of the time, sensitive teeth are caused by exposed dentin—the layer underneath your tooth’s hard enamel. Think of dentin like a sponge filled with tiny tunnels that lead directly to the nerves inside your tooth. When that dentin is exposed, hot, cold, or sweet foods can trigger pain fast.  Desensitizing Treatment seals those tiny tunnels.

Common reasons for dentin exposure include:


• Worn-down enamel (from brushing too hard, acid erosion, or grinding)
• Gum recession, where the roots of your teeth become exposed
• Cavities or tooth decay
• Chipped or cracked teeth
• Old or damaged fillings


The good news? Once we figure out what’s causing your sensitivity, we can treat it—often the same day.

At Danbury Smiles, we don’t guess—we diagnose. Here's what you can expect:

✅ A gentle dental exam to check for cavities, cracks, gum problems, or worn enamel
✅ A clear explanation of what’s causing your pain
✅ A custom plan with the best treatment options for your teeth

Depending on the cause, Dr. Landress may recommend one or more of the following:

This is a quick and easy procedure we do right here in our office. We apply a special liquid or gel to the sensitive area
that helps block pain signals—and it often gives you instant relief that lasts for months.


• Desensitizing Toothpaste
Some toothpastes are made to block nerve signals. We'll help you pick the most effective one (not all are created equal!).


• Fluoride Treatments
Fluoride strengthens enamel and can reduce pain over time. It’s great for protecting teeth from future sensitivity, too.


• Dental Bonding
For exposed roots or chipped teeth, we can use tooth-colored bonding material to seal the sensitive areas and stop the pain.


• Gum Grafting
If your gums have pulled away from your teeth, we may recommend a referral for a gum graft to cover exposed roots and
protect them from further damage.


• Root Canal Therapy
In cases of deep decay or nerve exposure, a root canal can remove the source of the pain completely and save the tooth.

Desensitizing treatment is often covered by dental insurance.  We’ll take care of the paperwork so you can focus on feeling better.
