Our bodies work differently. Some dental patients don’t react to local anesthetics by getting numb. This is understandably concerning when you need dental treatment. (And the word “concerning” may be a huge understatement!)
It’s important to know that bad experiences in the past don’t guarantee that you will never be able to become numb.
At Aspen Dental of Cache Valley, we take additional time and care with individuals who have historically had issues getting numb. Various methods used with different medications can overcome numbing conditions. We will find the accurate combination to make you comfortable.
Let’s look at the possible causes.
What Can Affect How I Respond To Numbing Medication?
A pH Imbalance
Your body’s pH level is a measure of the acidity or alkalinity in the blood and other fluids. Also called acid-base balance, the pH scale goes from 0 to 14. A pH below 7 is acidic. A pH above 7 is alkaline or basic. 7.40 is considered a normal blood pH. Your lungs and kidneys work continuously to control your pH balance.
When the pH level is abnormal, numbing agents can be less effective. Medical conditions such as asthma, emphysema, untreated diabetes, and cancer can impact pH levels.
An Acute Local Infection
This is related to the previous section because an infection alters the pH balance. If a dental patient has an infection in their mouth (sometimes called a hot tooth), it may need to be treated with antibiotics prior to dental treatment.
If painkilling medications wear off quickly, it could be due to an extra-active metabolism. Intensive exercise and caffeine can accelerate your metabolism. It’s best not to overdo either of these immediately before dental treatment.
Differences In Anatomy
When administering local anesthetics, dentists need to locate your nerve(s). But everyone is wired differently and X-rays don’t always give a clear picture of the location of nerves. The size and shape of your jaw and the amount of fat and muscle affect where nerves are located. Some men and women even have an extra nerve whereas most people have only one.
The Patient Moves During The Injection (We Want To Get On Your Nerves)
We get it. It’s not easy to stay perfectly still when your dentist is putting a needle into your mouth. But you want the painkiller sent to the nerve and it’s difficult to hit a moving target.
People with red hair and fair skin may need extra painkilling medication. This sounds wacky, but it is backed by science. The gene that produces hair color (Mc1R) also influences the pain receptors in the brain. The MC1R mutation that produces red hair is due to the production of pheomelanin. The presence of pheomelanin can exacerbate the body’s sensitivity to pain. This is another way people with auburn tresses are unique. But if you are a redhead who has avoided dental visits, please schedule an appointment by calling us at

Men and women who are extra nervous at the dentist may have difficulty getting numb. This could be due to a number of factors. Jaw clenching and holding your breath may change the way the body reacts to painkillers. Extreme anxiety may also affect the perception of pain even though there are no biological changes.
