 Dental Sedation Side Effects: What to Expect Afterwards

 

So you’ve booked in for a treatment with sedation, and now you’re wondering what the rest of the day will feel like.

 

Sedation wears off gradually, and most people find the after-effects are mild and pass within a few hours.

 

Below, we’ve set out the common dental sedation side effects, how long they tend to last, and the few signs that prompt a quick phone call, so you can plan your day and recover comfortably.

 Why you get side effects after sedation

Sedatives carry on working in your body for a while after your treatment is finished. Any grogginess or wobbliness you feel afterwards is the medication leaving your system, not a sign that something has gone wrong. It’s the same reason you might feel a little slow after a deep afternoon nap.

These everyday after-effects are quite different from the rare risks of sedation, which your dentist will talk through with you beforehand. Sedation itself is safe and used every day to help nervous patients feel at ease.

At Tooth Club we use two types of sedation: intravenous (IV) sedation and nitrous oxide, better known as laughing gas. The two work differently, so the way you feel afterwards depends on which one you’ve had. We’ll look at each in turn.

 Common dental sedation side effects

Most after-effects are minor and short-lived. The ones patients notice most often are:

  • Drowsiness or grogginess
  • Mild dizziness or feeling light-headed
  • Nausea, in some cases
  • A mild headache
  • A dry mouth
  • A fuzzy or patchy memory of the appointment

For most people, these fade within a few hours as the sedation clears. That last one, a hazy memory of the treatment itself, is common after IV sedation, and plenty of nervous patients count it as a bonus.

 Side effects by type of sedation

 Nitrous oxide (laughing gas)

Laughing gas is the lighter of the two options. You breathe it in through a small mask over your nose, and it usually leaves your system within 15 to 30 minutes of the mask coming off.

You might feel a little giddy or light-headed during treatment, but there’s not much to notice afterwards. Once your dentist is happy you’ve fully recovered, you can drive yourself home and carry on with your day.

 IV sedation

IV sedation gives a deeper sense of relaxation, delivered through a small drip in your arm. Because it’s stronger, the effects can linger for the rest of the day, and sometimes up to around 12 to 24 hours.

Feeling drowsy, a bit unsteady on your feet, or hazy about the details of your appointment is all to be expected. You’ll rest at the practice until you’re steady enough to leave, and you’ll need a friend or family member to take you home afterwards.

 How long do dental sedation side effects last?

It depends on which sedation you’ve had. With laughing gas, you’re usually back to normal within half an hour. With IV sedation, most people feel like themselves again within 24 hours, and often sooner.

How quickly it clears varies from person to person and depends on the dose, how long your appointment was, and your own body. If you’re still feeling groggy the next day, give yourself a little longer to rest before getting back to your usual routine.

 Recovering comfortably after sedation

A few things make the hours after IV sedation easier:

  • Arrange for someone to take you home, and ideally stay with you for a few hours
  • Take the rest of the day off and plan a quiet one
  • Avoid driving, alcohol, signing anything important, or using machinery for 24 hours
  • Sip water, and start with light, plain food if your stomach feels unsettled
  • Follow any specific aftercare your dentist gives you, for example after an extraction

After laughing gas, there’s less to think about, as it wears off so quickly, though it’s still sensible to take things gently for an hour or so.

 When to contact your dentist

Serious problems after dental sedation are rare, and the vast majority of patients recover without any issues. However, get in touch with your dentist if side effects are still hanging around well beyond 24 hours, if you’re being repeatedly sick, or if any pain isn’t settling with your usual pain relief. If you’re ever worried, our team would always rather you call and ask.

FAQs

Can you drive after dental sedation?

After laughing gas, you can usually drive yourself home once your dentist confirms it has fully worn off. After IV sedation, you must not drive for 24 hours and will need someone to take you home.

Laughing gas clears within about 15 to 30 minutes. IV sedation can take the rest of the day to wear off fully, with most people feeling normal again within 24 hours.

Mild nausea can happen with sedation, particularly IV sedation, though it isn’t the case for everyone. Sipping water and eating something light usually helps it settle.

No. Both laughing gas and IV sedation keep you conscious and able to respond, just deeply relaxed. It isn’t a general anaesthetic, so you won’t be put to sleep. However, with IV sedation, you may feel so relaxed that you drift in and out and remember little of the appointment afterwards.

In the UK, you’re usually advised to have a light meal, such as tea and toast, a few hours before IV sedation, along with small non-alcoholic drinks up to a couple of hours before. Before laughing gas, eating normally is generally fine, though it’s best to avoid a heavy meal. Your practice will give you exact instructions when you book.

Yes, though it’s best to wait until you feel steady and to start with something light and plain. If you’ve had a treatment such as an extraction, follow the specific aftercare advice your dentist gives you.
