IV Sedation vs Inhalation Sedation at a Leicester Dentist; Which Should You Choose?

Overview

Inhalation sedation uses nitrous oxide and oxygen through a soft nose mask. You stay fully awake, the effects clear within minutes, and you can drive yourself home. IV sedation is given through a vein in the hand and goes much deeper: you stay conscious but usually remember little or nothing afterwards. At EverySmile Dental in Leicester, IV suits severe anxiety or longer procedures; inhalation suits mild nerves and shorter treatments.

The appointment keeps getting pushed back. Not because there isn’t time, but because the thought of sitting in that chair brings on something that’s hard to explain to people who haven’t felt it. A kind of dread that starts the night before and doesn’t shift until you’re back home. For plenty of people across Leicester, that feeling has meant years of avoiding the dentist altogether.

Sedation dentistry exists for exactly this. Not as a last resort, but as a genuine clinical option that changes what’s possible. At EverySmile Dental, around 60 to 70 per cent of patients describe some level of dental anxiety. The team is built around this reality, which is why sedation options are offered as standard, not as something you have to fight to access.

The two most commonly used methods are IV sedation and inhalation sedation. They work differently, suit different situations, and produce different experiences. Dr Aisha Shabir at EverySmile works with anxious patients regularly and is well-placed to walk through what each one actually involves.

What Is the Difference Between IV Sedation and Inhalation Sedation at a Leicester Dentist?

This is the question that comes up most often before a first sedation appointment, and it’s worth answering properly rather than glossing over it.

Inhalation sedation uses a mixture of nitrous oxide and oxygen, delivered through a soft mask that sits over the nose. Within a few minutes, most patients notice a warm, floaty sensation and a significant reduction in how much they’re thinking about what’s happening. You stay completely awake and can respond normally to the dentist throughout. When the mask is removed, the effects clear within minutes.

IV sedation works differently. A small cannula is placed into a vein, usually on the back of the hand, and a sedative drug is administered directly into the bloodstream. The effect is much deeper. Patients remain technically conscious throughout — they can respond to verbal prompts if needed — but most have very little or no memory of the procedure afterwards. The feeling is often described as being on the edge of sleep without actually crossing over.

Both are forms of conscious sedation. Neither involves a general anaesthetic, and neither requires a hospital setting.

Inhalation Sedation: Who It Works Well For

Inhalation sedation suits patients with mild to moderate anxiety who want something to take the edge off without losing awareness of what’s happening. It’s also well-suited to shorter appointments, such as a filling, a hygiene treatment, or a straightforward extraction.

One of its practical advantages is the recovery time. Because the nitrous oxide clears from your system so quickly, you can drive yourself home afterwards and return to normal activity on the same day. There’s no need to arrange someone to collect you, which makes it far easier to fit around work or a school pick-up.

For children, inhalation sedation is often the first-line option. EverySmile offers it for young patients who need a little extra support, and the team’s experience with anxious children means the approach is slow, patient-led and never rushed.

The sensation varies by person, but most patients describe it as pleasant: a warmth in the hands and feet, a loosening of tension, a sense that everything matters slightly less than it did a few minutes ago. Some feel light-headed. Most feel calm.

IV Sedation: Who It Works Well For

IV sedation is the option for patients with significant dental phobia, those who’ve had previous traumatic dental experiences, or anyone facing a longer or more complex procedure — implant surgery, multiple extractions, or treatment that would otherwise require several separate appointments.

The depth of sedation is meaningfully greater than inhalation. Most patients who’ve had IV sedation describe waking up, in effect, with no recollection of the treatment. The dentist has been working, time has passed, and none of it registered. For someone who has spent years dreading the chair, this can be the thing that finally makes treatment feel possible.

You cannot drive after IV sedation. You’ll need someone to collect you and stay with you for the remainder of the day. The sedative affects coordination and judgement for several hours after the appointment, so no driving, no important decisions, and no operating machinery until the following day.

EverySmile uses IV sedation for procedures including dental implants, complex extractions and multi-stage treatments. Patients from Oadby, Birstall, Groby and further out regularly come to the practice specifically for sedation treatment, knowing the environment is set up to support anxious patients from the moment they arrive.

Will I Be Unconscious with IV Sedation at a Dentist?

This is the single most common misconception about IV sedation, and it matters because it stops some patients from pursuing treatment they’d genuinely benefit from.

IV sedation does not make you unconscious. You remain conscious throughout, meaning you can breathe independently, respond if asked a question and move if necessary. What it does is place you in a state of very deep calm, often called twilight sedation, where you are aware enough to cooperate but far too relaxed to be distressed.

The amnesia effect — the reason most patients have no memory of the procedure — is a side effect of the sedative drug rather than unconsciousness. Your brain is simply not storing the experience in any meaningful way. It’s similar to how some people have no recollection of the early part of waking up even though they were technically awake.

General anaesthesia, which does produce full unconsciousness, is a different clinical process entirely and is not offered in a dental practice setting.

Choosing Between the Two Options at EverySmile

The right choice depends on the patient’s anxiety level, the treatment being carried out and practical factors like transport. Neither option is better in an absolute sense; they serve different needs.

For someone with mild nerves who needs a filling and can drive themselves home, inhalation sedation is likely the more practical fit. For someone who hasn’t been to the dentist in eight years because the thought alone causes panic, and who needs extractions or implant work, IV sedation is worth a proper conversation.

At EverySmile, the sedation conversation happens before any booking is made. The team will ask about your anxiety history, what’s happened at previous appointments, what treatment is planned and what your practical circumstances look like on the day. The recommendation comes from that conversation, not from a fixed protocol.

Preparing for a Sedation Appointment at EverySmile

Both sedation types require some preparation, though the requirements differ.

For inhalation sedation, preparation is minimal. You can eat and drink normally beforehand, and no escort is needed for the journey home.

For IV sedation, you’ll need to fast for several hours before the appointment — typically no food for six hours and no clear fluids for two hours. You’ll also need someone to bring you and take you home, and you should plan to rest for the remainder of the day. The EverySmile team will go through the full pre-appointment instructions when you book so nothing comes as a surprise.

Across Leicester and surrounding areas including Kirby Muxloe, Narborough and Kibworth, patients often book sedation appointments for the extended evening slots on Mondays and Wednesdays. Arriving with time to spare, without the pressure of rushing, tends to make the appointment itself go more smoothly.
