The Dental Routine That Survives a 12-Hour Day

Of course no one forgets to brush their teeth deliberately. What actually happens is much more mundane: you leave the flat at 6:40am, have your lunch at your desk, arrive home at nine, and manage to stand over the sink at 11:15 with half-closed eyes. It isn't that there's anything wrong with this routine, exactly, just that it leaves little room for two minutes of teeth-cleaning.

Instead of trying to think of additional things to do, it's probably best to make the things you already do a little bit harder to avoid, and to understand what you should be trying to accomplish with them.

Two minutes, twice a day - and what to do in them

Brush last thing before bed, and once more somewhere in the day, using fluoride toothpaste (at least 1350ppm for most adults, which is what you'll find in most supermarket brands; if you buy 'premium' brands, check the packet). The issue with brushing is not time spent, but technique: tilt the brush at an angle of around 45 degrees to the gums, not straight down, and avoid long strokes back and forth. Hard scrubbing will not get your teeth whiter, and will over years damage your gums and wear down your teeth, and a soft or medium brush is just as effective as a hard one.

Once you've finished, spit, and avoid rinsing, to preserve the fluoride coating on your teeth; use mouthwash if you want it, just not straight after the brush. Two other things to consider:

        Replace your brush or brush heads roughly every three months, or when the bristles start to splay outwards. Your teeth are not getting the clean they deserve if you leave it longer: the decrease in effectiveness is gradual enough that you might not notice it at all.

        Electric brushes, used correctly, have a small advantage over manual ones: systematic reviews by the Cochrane collaboration suggest they decrease plaque and gingivitis slightly, with oscillating-rotating brushes being the most effective. The advantage is small, but it is still an advantage, and a good manual brush used properly can also be effective.

The part almost everyone forgets

A toothbrush only gets at about three of the five surfaces of each tooth, leaving the two sides - the interdental spaces - exposed. This means that food and bacteria can accumulate in these pockets, leading to decay in the spaces between the teeth and gum disease. This is why cleaning between your teeth is such a huge priority: it covers the places your toothbrush can't, and only takes a minute or two a day.

Interdental brushes are usually a good option where the space permits, and should be used once a day, ideally before your brush. They're much faster than flossing - once you know your sizes (yes, they come in sets) it takes 30 to 60 seconds to clean all the way between your teeth. It's a question of sizes: it should be tight enough to feel some resistance as it moves through, and loose enough that you aren't damaging your gums. A hygienist should be able to tell you what sizes you need for your mouth in under a minute, and there's a decent chance you'll need more than one. Where there is no space (often on the lower front teeth), flossing is a better option.

Once you've done this, your fluoride toothpaste should be getting into those harder-to-reach places to remineralize the enamel. If you haven't been cleaning between your teeth much before this, you may notice some bleeding, which is caused by inflamed gums. As you continue cleaning, the irritation should go away after a week or two, and if it doesn't, then it might be a reason to mention to your dentist. Don't just stop cleaning between your teeth, though: if it's been two or three weeks and your gums still bleed, that's something to consider.

Frequency matters more than amount

When it comes to sugar and teeth, it's not really about how much sugar you eat, but how often. Every time sugar is introduced to the mouth, the pH drops for a short period, until the body produces more saliva to balance it out. A piece of cake eaten over ten minutes is one spike, but a 500ml bottle of sweetened soda drunk over an hour is more like six.

It's not hard to see how the office environment might increase this risk: two coffees, one energy drink at lunch, the brownies brought in by your colleague, and a flat white on the way back from a meeting all add up. None of this is really much at once, but all of it added together means extra acid exposure for your teeth throughout the day.

Again, the solution doesn't really involve limiting yourself much: keep any sweet foods and drinks to mealtimes, and try to drink water at your desk. Sugar-free gum after lunch can help stimulate the production of saliva, which helps neutralize the acid. If you've had something acidic - fizzy water, lemon or lime juice, wine, or cola - wait an hour before brushing your teeth, to avoid dissolving away the protective enamel layer.

Gum disease rarely hurts until it's too late

Gum disease is unusual in that its early stages rarely present with any pain - in fact, there shouldn't be much pain at all. Bleeding gums after brushing, visibly inflamed gums, persistent bad breath, and teeth becoming loose or appearing longer than usual, are all warning signs and reasons to see a dentist, but none of these should be immediately painful. If it's not hurting, there's no reason to put it off. The reason to visit Surrey Docks Dental Practice in Canary Wharf earlier rather than later is that gum disease is much easier to treat in its early stages and prevent it from getting to the point where the bones are deteriorating.

Smoking is much more likely to contribute to gum disease, and can also reduce the bleeding from gums that would normally be an obvious sign. Poorly managed diabetes makes the gums more susceptible to infection, and dry mouth (often a side-effect of antidepressants and other common medications) causes an increased risk of cavities because the saliva isn't doing its job of sweeping food and bacteria away. All of these are worth mentioning to a dentist, because they can affect the treatment plan - and how often you should be coming in - accordingly.

Appointments: how often, and why it matters

There is no real set guideline for how often you should be going to the dentist, apart from the general 'every six months'. The national guidance (NICE) sets out rough ranges depending on an individual's risk factors: the frequency can vary anywhere from three to 24 months for most people, depending on their oral health and how well they're able to care for their teeth at home. Someone with healthy gums and few fillings may be able to go 18 months between cleanings, whereas someone with more serious conditions may need to be seen more frequently.

The reality for most people is that they find it very difficult to schedule in a 2pm appointment in another part of town, and then remember to cancel it when they go on holiday. The real solution is to book with a practice that is local to you, where you can be seen without having to rearrange your entire week. That way, you'll be much more likely to keep your appointment - if you're in or around Canary Wharf, you could consider Surrey Docks Dental Practice in Canary Wharf. Make sure to book your next appointment before you leave your current one, so that it's all set in stone by the time you get there.

On whitening, briefly

Whitening treatments only address the color of the teeth, not any underlying issues such as cavities or gum disease, and won't effectively treat heavily discoloured teeth (which should be professionally cleaned before whitening). It's a worthwhile treatment to consider, just not as a substitute for a regular dental examination.

Make the routine portable

Busy days are easier to manage when the basics are already within reach. If you regularly stay late at work, travel, or spend nights away from home, keeping a spare toothbrush, fluoride toothpaste, and whatever you normally use to clean between your teeth can remove one more excuse for skipping the routine. The essentials do not change just because the setting does: brushing twice a day and cleaning between the teeth regularly remain the core habits.

In short

Brush twice a day with fluoride toothpaste, and clean in between your teeth once a day, and make sure to keep sugary foods and drinks to mealtimes. Visit the dentist as often as they recommend, based on your own personal circumstances – which, for most people, will be every six months to a year. This all takes less than five minutes a day, and is worth it for the long-term benefits.
