If it has been a while, the not knowing is often worse than the appointment. A first visit at a new practice is mostly conversation, looking and measuring. Very little is done to you on day one.
Here is the whole thing, in order, so nothing is a surprise.
Before you go
Expect to fill in a medical history. It matters more than people expect, because conditions like diabetes, pregnancy, heart valve problems and medicines such as blood thinners or bone density drugs change how treatment is planned. Bring a list of what you take, including anything over the counter.
If you have X-rays from a previous dentist taken in the last year or two, ask for copies and bring them. They are yours, and it can save you a repeat set.
Write down the medicines you take, including anything you buy over the counter, and any conditions you are being treated for. Dentists ask because it changes what they do: blood thinners matter before an extraction, some medications dry your mouth and raise your decay risk, and a heart condition can change the plan. It is quicker to hand over a list than to remember under a spotlight.
The exam itself
The dentist looks at each tooth for decay, cracks and failing old fillings, and checks the fit of any crowns or bridges. They check your gums by measuring the depth of the small gap around each tooth with a probe, which is where those numbers being called out come from. One to three is generally healthy, four and above suggests gum disease.
They also check the soft tissue: cheeks, tongue, floor of the mouth and throat, which is a screening for oral cancer and takes under a minute. And they look at how your teeth meet, since a bite that grinds tells its own story about the wear they can see.
X-rays, and why they are not taken every time
X-rays show what the eye cannot: decay between teeth, infection at the root, bone levels and unerupted teeth. A new patient usually needs a set, because the practice is starting without history.
After that, the interval depends on your risk. Somebody with no decay for a decade needs them far less often than somebody with active problems. If you are told you need X-rays at every visit as routine, it is reasonable to ask why.
The cleaning
A routine cleaning removes plaque and hardened deposits above the gumline, then polishes. It may be done by a hygienist rather than the dentist, and it usually takes half an hour to an hour. Some tenderness afterwards is normal, particularly if it has been a while.
If your gums bleed heavily and the measurements come back deep, you may be advised to have a deep cleaning instead, which is a different appointment, usually with numbing. That is a genuine clinical decision, not a sales tactic, but you are entitled to have it explained in terms of your own numbers.
The plan and the money
At the end you should get a clear account of what they found, what needs doing, what is urgent and what is watch and wait. Ask for it in writing with the costs, and ask what happens if you delay each item. The answers separate genuine urgency from things that are simply on the list.
A good first visit ends with you knowing three things: what state your mouth is in, what the next step is, and what it will cost.

If the plan comes to more than you were expecting, ask which parts are urgent and which can wait. There is almost always an order to it: pain and infection first, then the things that will become painful, then the rest. A dentist who cannot be drawn on that ordering, or who wants the whole plan agreed today, is telling you something useful about how they work.
- What did you find, and what is urgent versus optional?
- What happens if I wait six months on this one?
- What will my share be after insurance?
- How often do you want to see me, and why that interval?
The short version
- A first visit is mostly examination and conversation, not treatment.
- Bring a medicines list and any recent X-rays, which belong to you.
- Gum measurements of one to three are generally healthy, four and above need attention.
- X-ray frequency should follow your risk, not a fixed routine.
- Leave with a written plan, costs, and a sense of what is urgent.

Frequently asked
How long does a new patient appointment take?
Usually forty five minutes to an hour and a half, depending on whether the cleaning happens the same day. Some practices split the exam and the cleaning into two visits, especially if they are busy or if your gums need more time.
Will they judge me if I have not been in years?
A good practice will not, and they see it constantly. Say so when you book. It lets them allow more time and start gently, and it usually makes the appointment easier for everybody.
Can I ask them to stop partway through?
Yes, always. Agree a signal, usually raising a hand, before they start. Any dentist worth staying with will stop immediately and check on you.
