Your first weeks with a new denture: what helps and what is normal

A new denture (Prothese) is not something you put in and forget; it is something you learn, and the learning takes weeks rather than days. Almost everyone finds the first days odd — too much saliva, a full-feeling mouth, a tongue that will not leave the new object alone, speech that sounds wrong in your own ears. Most of that settles within two to four weeks as the muscles reorganise around the new shape. Sore spots (Druckstellen) are the exception: they do not resolve on their own, they are corrected in a short adjustment appointment, and those appointments are a planned part of the treatment rather than evidence that something went wrong. The two commonest mistakes in the first month are leaving the denture in a drawer because it feels strange, and filing down a rubbing edge at home. Wear it, eat carefully, and let the practice do the adjusting.

Your mouth is one of the most precisely mapped areas of the body — the tongue registers differences of a few hundredths of a millimetre, which is why a filling that sits a fraction too high feels like a boulder. Into that finely calibrated space you have introduced a large new object, and the nervous system does what it should: it investigates. That accounts for most of the early complaints, and all of them are predictable.

More saliva than usual, for a few days, while the glands treat the denture as something to be dealt with. It settles by itself.

A full, bulky feeling, particularly with an upper full denture covering the palate, and a tongue that keeps checking. Both fade once you stop consciously monitoring them.

Dulled taste and temperature sense. An upper plate over the palate reduces how much heat you register, so test hot drinks and soup with your lips first — the usual early-warning system is partly switched off.

Gagging, more common with an upper denture and usually short-lived. Nose breathing and simply keeping the denture in for longer stretches both help. If it persists beyond the first weeks, tell us: the shape of the back edge can often be modified.

Wear the denture as much as you can tolerate, take it out to clean, and lower your expectations about food: liquids and soft food only, nothing needing a real bite. This is the hardest stretch and the shortest one.

Sore spots appear now, usually at predictable places along the border of the denture, and this is where the first review appointment normally sits. Keep it even if nothing hurts — and especially if something does. Food gets more ambitious: minced, flaked, cut small. Speech starts to correct itself if you practise.

Chewing becomes reasonably efficient and most people stop thinking about the denture during ordinary conversation. New pressure points can still appear as the tissue settles, and they are still an appointment rather than a DIY job. Adaptation is individual, though: age, saliva, the shape of the jaw ridge and previous denture experience all influence the pace, and nobody can promise a particular week in which everything will feel normal.

Chewing with a denture is a different mechanical task, not a weaker version of the old one, and the full method has an article of its own: Can you eat normally with a denture?. For the settling-in period, two habits carry most of the benefit.

Bite at the side, never at the front. Biting into an apple or a crusty Brötchen with the front teeth levers the back of an upper plate downwards. Cut food into segments and take it in at the side teeth instead.

Chew on both sides at once. Counter-intuitive, but even pressure keeps the denture seated, whereas working one side tips it.

Otherwise: soft food for the first days, then minced and softened food, then ordinary meals as confidence returns.

Speech recovers with practice, and the practice can be pleasant: read aloud for ten minutes a day. The sounds needing the tongue against the palate or the upper front teeth — s, sh, f, v, t, d — misbehave first and recover first.

There is a wrinkle here that matters if you live in Germany without German as your first language: you are re-learning two sound systems at once. English th, which does not exist in German, forms right at the edge of the upper denture and feels alien for a week or two. German z (a ts sound), ch as in ich and the German r all use tongue positions that shift when the palate is covered. Practising in one language only leaves you fluent in that one and hesitant in the other.

One practical tip: record thirty seconds of yourself on your phone in each language in week one and again in week three. The improvement is far clearer on the recording than in your own ear.

A Druckstelle is a small area where the denture presses too hard on the mucosa. It feels like an ulcer, it often appears two to five days in, and it is entirely normal at the start — the denture was made on a model, and your mouth is not a model.

What matters is what you do about it.

Do not file, sand, trim or heat the denture at home. A millimetre removed in the wrong place ruins the fit permanently, and a denture with a modified edge often cannot be corrected afterwards. This is the most expensive mistake of the whole adaptation period.

Do not simply stop wearing it either. The sore area heals, the swelling settles, and by the time you reach the appointment nobody can see where the problem was. Do the opposite: wear it for a few hours before you come in, so the irritated spot is visible and we can relieve exactly the right place. Take it out overnight if the area is raw, unless you were told otherwise, and rinse with lukewarm salt water.

Expect more than one appointment. Two or three adjustment visits in the first weeks are routine rather than a complaint. They are short, they normally need no anaesthetic, and with an in-house master dental laboratory (Meisterlabor) small corrections do not involve posting anything anywhere — how the making and fitting of a denture is organised here is described on Dentures and prosthetics – service page (EN).

If you need to book that appointment in German, these sentences do most of the work:

We work in English as well as German, Russian, Turkish, Ukrainian, Arabic, Kurdish and French, so you do not need those sentences with us — but they are useful anywhere in the system, and for many patients around Wuppertal, Düsseldorf, Cologne and Bonn the language question is the reason they changed practice in the first place: English-Speaking Dentist in NRW.

The full routine is set out separately — How to clean a denture without damaging it — but four errors are made almost exclusively in the first weeks, when the habits are still forming.

Ordinary toothpaste. Most toothpastes are abrasive enough to scratch acrylic, and scratches hold stain and plaque. Use a denture brush with mild liquid soap or a purpose-made denture cleaner instead.

Cleaning over a hard sink. Fill the basin with water or lay down a folded towel first. A dropped denture on bathroom tiles is one of the commonest causes of a fractured base.

Hot water. It can distort the base, and a distorted base no longer fits. Lukewarm only.

Forgetting what is underneath. Brush the gums and palate with a soft brush, and clean any remaining natural teeth and clasps meticulously — the teeth carrying a partial denture (Teilprothese) are under more load than any others in your mouth.

Give the tissue a rest, ideally overnight, unless you were told otherwise: continuous day-and-night wear is associated with sore, inflamed mucosa and fungal irritation, and German dental associations consistently recommend a daily rest period.

Denture adhesive (Haftcreme) has a legitimate place — a thin application adds confidence in the first weeks, particularly for a lower full denture, which sits on a narrow ridge with physics working against it. It is not a solution to a denture that does not fit. Needing progressively more of it to get through the day is diagnostic information: something has changed, usually the jaw ridge underneath, and the answer is a reline (Unterfütterung) or an adjustment rather than a bigger tube. Apply it in small dots, clean it off completely every evening, and tell us you are using it.

Our opening hours are Monday to Friday 07:30–19:30 and Saturday 08:00–18:00, and outside those times Germany’s dental out-of-hours service (Notdienst) exists for urgent problems.

A dry mouth. Saliva is what holds an upper denture in place, so anything that reduces it — many blood pressure tablets, antidepressants, antihistamines, diuretics — makes wearing one harder. Bring your medication list; sipping water and saliva substitutes help, and the design can allow for it.

Diabetes. Well-controlled diabetes is no obstacle. Poorly controlled blood sugar makes the mucosa more vulnerable to pressure and to fungal infection, so sore spots deserve quicker attention.

Caring for someone else. If you are helping a relative through this, the two measures that make the biggest practical difference are labelling the storage box and keeping the cleaning routine written down on the bathroom shelf. Dentures go missing in care settings with remarkable regularity. Dental anxiety belongs in the same conversation: say so when booking, and longer appointments, step-by-step explanation and sedation or laughing gas (Lachgas) are all available.

New to Germany with a denture made abroad. It can usually be assessed, cleaned, adjusted and often relined here. What travels less well is the paperwork: a warranty from another country generally does not apply, and any German subsidy is tied to a treatment and cost plan (Heil- und Kostenplan, HKP) submitted here before work begins. Bring what documentation you have.
