The local anesthetics we use most often – lidocaine, septocaine, and carbocaine – are generally very safe. But when combined with certain substances, the risks can become serious and, in some cases, life-threatening.
Below, we explain why we ask and what you should know:
Cocaine and Dental Anesthetics: A Dangerous Mix
If you have used cocaine recently, please tell us. Cocaine and local anesthetics like lidocaine, septocaine, and carbocaine can cause dangerous heart rhythm disturbances, spikes in blood pressure, or even death when combined.
This is not about getting you into trouble. We simply need to know so that we can delay your procedure or use different methods to keep you safe.
Methamphetamines and Dental Anesthetics
Methamphetamine use can be extremely dangerous when combined with lidocaine, septocaine, or carbocaine. Meth can significantly increase heart rate and blood pressure, and when anesthetics are added, the risks for serious cardiovascular events skyrocket.
As with cocaine, if you have used meth recently, we need to delay treatment until it’s safe.
Marijuana (Weed) and Dental Anesthetics
We know that marijuana is legal in Arizona, and we are not upset if you smoked or took edibles before your appointment. However, marijuana can affect how well and how quickly local anesthetics work.
Patients who use cannabis may experience delayed or reduced numbing effects, which can mean that you feel pain during the procedure if we start too soon. If we know ahead of time, we can give the anesthetic more time to work or adjust the dosage so that you stay comfortable.
Opiates and Dental Anesthetics
Opiates (like prescription painkillers, heroin, or fentanyl) can also interfere with the way local anesthetics work. In some cases, patients using opiates may require a higher dose of anesthetic to achieve the same numbing effect.
If you’re using opiates, please let us know. We are only interested in keeping you comfortable and safe.
Alcohol and Dental Procedures
Alcohol may be legal, but drinking before your dental appointment can also pose risks. Alcohol thins your blood, which can lead to excessive bleeding during dental procedures, especially those involving extractions or gum work. It can also interact with sedatives or pain medications, making you feel dizzy or sick.
If you’ve had a few drinks before your appointment, let us know. In some cases, we may need to reschedule your treatment to protect your safety.
Your Safety Is the Priority
We understand that these are sensitive questions, but your health and safety come first. Knowing what substances may be in your system allows us to:
- Prevent dangerous interactions
- Keep your heart rate and blood pressure stable
- Ensure that numbing medications actually work before we begin treatment
Please be honest with us – no matter what. Our goal is to help you, not to judge you.
Bottom line: If you’ve used any recreational or prescription drugs, legal or illegal, recently, let us know. We can adjust your care so that your dental visit is as safe and comfortable as possible.
