It is much more common to be anxious about visiting the dentist than many people realize. Some of our patients have had a bad experience before, while others may struggle with needles, gag reflexes, or just sitting in the chair. We are the dentist in Brighton that has been trusted by local families for over 50 years, and we have learned that learning about your sedation options is often the first step.

Two of the options we talk about most often are happy gas (nitrous oxide) and IV sedation. Both help you relax during treatment, but they work very differently. Below, we explain how each one works, what it feels like, and which situations each tends to suit.

What Is Happy Gas?

Happy gas is made up of nitrous oxide together with oxygen. It is administered through a tiny nose mask, and within a few minutes most patients become calm, relaxed, and feel a bit “floaty”. Some patients report feeling a tingling sensation in their hands and feet.

It does not put you to sleep but leaves you awake to respond to our questions and follow any simple instructions. It does not numb your teeth, and hence we still administer local anaesthesia in places where it is needed. The best thing about it is that it helps reduce anxiety and the procedure becomes more comfortable.

The great benefit of happy gas is that its effects wear off quickly, and as soon as the procedure is complete, we change the gas from nitrous oxide to pure oxygen. In most cases, patients can resume their daily activities immediately after we confirm that all its effects have worn off.

Happy gas is often a good fit for:

• Mild to moderate dental anxiety

• Shorter appointments, such as fillings or cleans

• Patients who feel uneasy about needles and injections

• Children who need a little extra help to relax (where suitable)

• People who need to get back to work or drive afterwards

What Is IV Sedation?

IV (intravenous) sedation involves giving sedative medication through a small cannula, usually placed in the back of your hand or your arm. At Lifestyle Smiles, IV sedation is administered by an anaesthetist, while our dentist focuses entirely on your treatment.

IV sedation creates a much deeper level of relaxation than happy gas. You're still breathing on your own and can usually respond to simple requests. However, most patients feel drowsy and dreamlike, and many remember very little of the appointment afterwards. That's why people often call it "sleep dentistry," even though you aren't under a general anaesthetic.

Throughout the procedure, we closely monitor your oxygen levels, blood pressure and heart rate. The anaesthetist can adjust the level of sedation as treatment goes on, so you stay comfortable from start to finish.

If you're worried about the needle itself, we can use happy gas first to help you relax before the cannula goes in.

IV sedation is often considered for:

• Severe dental anxiety or dental phobia

• Longer or more complex procedures, such as dental implants or wisdom teeth removal

• Patients who need several treatments completed in one visit

• A strong gag reflex that makes treatment difficult

• Some patients with conditions that make sitting still for long periods challenging

There's also a middle-ground option: oral sedation. This involves taking a prescribed anti-anxiety tablet before your appointment. It helps you feel calmer when you arrive, but it takes longer to work and its effects are less predictable than IV sedation. As with IV sedation, you'll need someone to bring you in and take you home.

Preparing for Your Appointment

How you prepare depends on which option you choose.

For happy gas, a light meal a couple of hours beforehand is usually fine. Wear comfortable clothing, and let us know if you have a blocked nose or a cold, since you need to breathe comfortably through your nose.

For IV sedation, we'll give you clear fasting instructions ahead of time. Please follow them closely, because they're important for your safety. You'll also need:

• A responsible adult to take you home and ideally stay with you for the rest of the day

• To avoid driving, operating machinery, drinking alcohol or signing important documents for the rest of the day, or longer if advised

• To wear loose, comfortable clothing so monitoring equipment can be attached easily

• To plan a quiet day at home to rest

Is Sedation Safe?

Happy gas and IV sedation have both been around for a long time and are both very safe in dental practices. Like any other treatment, there are potential risks involved. Before making any recommendations, we discuss your medical background and overall health.

Several issues may determine the suitability of a specific kind of sedation. These include pregnancy, certain lung or heart diseases, and some drugs. For this reason, we always go over all of your treatment options and make sure you know everything that is expected.

How Do You Choose?

Choosing between happy gas and IV sedation usually comes down to three things:

1. How anxious you feel. Mild nerves often respond well to happy gas. Deep-seated fear may call for IV sedation.

2. What treatment you need. A quick filling and a multi-hour implant procedure call for very different approaches.

3. Your health and lifestyle. Your medical history, and whether you need to drive or return to work afterwards, both matter.

There's no right or wrong choice. The goal is simply to find the option that helps you feel safe and comfortable. We'll recommend what we think suits you, but the decision is always made together.
