Severe mucositis


In case of severe pain, it may not be possible to use toothpastes or toothbrushes. Try to sip chamomile, thyme or bicarbonate infusions throughout the day.

Keep your lips moisturized with lip balm or olive oil to prevent them from chapping or drying out.

It is recommended to drink about two liters of water a day, infusions, non-acidic fruit juices, broths, gelatins, polos… If it is painful, you must take small sips throughout the day and use a cane to direct the liquids to the less painful areas.

Choose preparations and foods in small volumes and with a high nutritional value. You must try to maintain the intake and remember the importance of ensuring a complete diet.


  • Alcoholic drinks, coffee, fizzy drinks and other acidic or irritating soft drinks (cola drinks).
  • Acidic foods (tomato, raw pepper, kiwi, lemon, orange, strawberry, tangerine, mango, pineapple, vinegar, vinegared foods…).
  • Highly seasoned, spicy or salty foods.
  • Dry or thick foods (crusted bread, toast, biscuits, sticks, dried fruit, dry biscuits, crisps, dry or very cured cheeses and baked or gratin-type dishes).
  • Pasty foods (such as mashed potatoes, croquettes, banana, chocolate…).
  • Fibrous foods, such as some grilled meats or asparagus.

In case of intense pain, it is necessary to prioritize purees and crushed food to achieve a suitable texture that ensures sufficient intake. If you start with solid foods, it is possible that your mouth will be so sore that you will not be able to eat even the crushed ones. Crushing does not always have to be equivalent to mash, but can be a suitable texture, although solid, as long as it is very soft, such as custards, puddings, fish cakes, crushed textured with agar-agar…

Crushed food does not mean that you stop eating what you like, you just need to adapt the texture. Almost all preparations and dishes of a standard diet can be adapted to a crushed texture, and therefore it is not always necessary to prepare special preparations for the person who has to eat crushed food. So, the typical and most common dishes of our diet can be adapted without much difficulty, allowing the whole family to continue eating the same thing.

Proteins are essential throughout the treatment process, so purees must include meat, fish, eggs or plant-based protein, such as soy, both at lunch and dinner. You should try to prepare a single dish that contains all the food groups.

It is recommended to make a single grind of about 300 ml (medium bowl) at most. You can also prepare two small triturates, dividing the amount and simulating a first and second course. When eating crushed it can be more difficult to finish the dish, as the texture and color can be boring, so it is important to mix different textures or consistencies and colors.

Its contribution of vitamins and bioactive compounds are essential during the treatment. You must consume soups or cold vegetable purees, such as gazpacho or salmorejo, prepare salads and grind them, and also prepare fruit purees with one or more fruits.
