About

One dentist,writing it down

This site is written by one person rather than a practice. It takes no appointments, sells nothing, and exists for the ten minutes after a dental appointment when most of what was said falls out of your head.

You can leave a dental appointment with a reasonable idea of what was done and a much vaguer idea of why.

The explanation happens while you are lying down, half numb, with somebody’s hands in your mouth and a suction tube running. It is not a good moment for taking anything in, and it is nobody’s fault that it does not stick.

So I write the version you can read afterwards, or beforehand, at your own pace, with nothing being done to you while you read. It covers the things people want to know and often do not ask: what the noise is, how long it takes, whether it will hurt, what happens if you leave it.

There are two halves to it. The guides explain how teeth work and what goes wrong with them. The before-and-after pages are narrower and more practical — what a particular appointment involves, and what to do in the days after it. The second half is the part people come back for at eleven at night, which is why it is written to be found in two taps and read in one hand.

The mechanism, not just the instruction

Schematic. An illustrative model of the mechanism, not measured data.

  • Eaten in one sitting. One sugar occasion, one acid attack.
  • In squares, across the afternoon. 6 occasions, 6 acid attacks.

In this model the first afternoon spends about 11 minutes below the threshold and the second about 66. Those figures describe the model, not a measured mouth.

Every occasion here is given the same depth of challenge, which is what isolates frequency. A smaller portion need not take pH as low, and the amount of sugar matters as well as the pattern of it.

Fig. 01Plaque pH across one afternoon, given the same amount of sugar two ways. Eaten in one sitting it is a single acid attack; in squares across the afternoon it is six — and because recovery is slower than the gaps between them, each attack begins before the last has finished clearing. That is the shape of nearly every page here: not eat less sugar, but why how often matters as well as how much.The curve is modelled rather than measured: the resting and minimum values, the recovery rate and the spacing are illustrative ones chosen to show the mechanism. The threshold is drawn at the customary pH 5.5, which is a teaching figure rather than a fixed constant: the point at which enamel begins to lose mineral depends on how much calcium and phosphate the fluid at the tooth surface holds, and because plaque fluid holds more of both than saliva does, under plaque it can be nearer pH 5.1.

How these are written

6 rules every page is held to

  1. 01

    Plain English, and no hedging into uselessness

    Technical words are used where they are the right word, and explained the first time. Where something genuinely varies between people, it says so, rather than offering a tidy number that happens to be wrong for you.

  2. 02

    The mechanism, not just the instruction

    Telling someone not to rinse after brushing is an instruction they will forget. Telling them rinsing washes the fluoride off is a reason they will keep. Nearly every page here is built that way.

  3. 03

    UK practice, UK guidance

    Fluoride concentrations, NHS entitlements, how wisdom teeth are assessed and what is free during pregnancy are all specific to the UK. Advice written for another healthcare system can be confidently wrong here.

  4. 04

    Safety-netting, always

    Anything describing a symptom says plainly when to stop reading and be seen — and at which level. An emergency department, an urgent dental appointment and 999 are three different answers, and the aftercare pages separate them rather than sending everybody to hospital.

  5. 05

    Where the sources disagree, it says so

    NHS trust leaflets contradict each other on how long to bite on a socket, how much salt to use and for how many days. Where that happens, the page gives one defensible answer and names the disagreement rather than implying a consensus that does not exist.

  6. 06

    Your dentist comes first, and no selling

    Nothing here recommends a brand, and nothing is written to sell a treatment. Where the honest answer is that an expensive option is no better than a cheap one, it says that. And where anything here differs from what the dentist treating you said, follow them — they examined you and this did not.

What this is not

This is an independent dental information site. It is not a dental practice and does not offer appointments, treatment, prices or emergency care. Nothing here is a diagnosis, and reading it does not make anyone your dentist. Its one purpose is to explain dentistry clearly enough that you can have a better conversation with the person who does treat you.

  • Not a diagnosis. A page can tell you what a sign usually means. It cannot tell you what is happening in your mouth.
  • Not a substitute for being examined. Much of what matters is invisible without an X-ray and a pair of eyes.
  • Not urgent care. If you are in pain now, ring your own practice — and if you cannot reach one, the route for each of the four UK nations is on the urgent care page. Call 999 if breathing or swallowing is affected.
  • Not personalised. Your age, medical history and what is already in your mouth all change the answer.
  • Not me being your dentist. Reading this does not make it so, and I cannot advise you about your own teeth.

Who writes this
