Side effects

Side effects: What to do if you have a complaint about:

Local anaesthetic

If you have had an anaesthetic for one of our dental treatments, you should be aware of the following:
A regular local anaesthetic should last approximately three hours. Then sensation should return. Sometimes, more local anaesthetic must be used, meaning it may last longer. If the area is still numb the following day, please contact us immediately.


Burden of your filling? Contact the dentist in The HagueYou may suffer from lingering pain after a filling. This can be exacerbated when eating and drinking hot and/ r cold foods/beverages. This may be a reaction of the filling (especially white fillings), but should disappear within a few days. You may take an analgesic like paracetamol. Should the pain worsen, or start spontaneously at night
and if the part of the cheek nearest to the filling begins to swell, you should contact us.


Pain complaints or side effects with pulled teeth? Call the dentist in The HagueIf you have had one or more teeth pulled, it is advisable to do the following after treatment:

Keep the compress on the wound for half an hour and bite down on it hard. If the wound bleeds later on, put another compress onto the wound and bite down on it for another half hour. The wound heals best when the blood can clot easily. Do not swill your mouth on the first day. As from the second day you can brush the teeth as usual, but avoiding the painful areas and where the wound is located. Rinse your mouth with lukewarm salty water.

Once the anaesthetic has worn off, you can eat and drink again, but try to use the opposite side of the mouth. Food and drink should not be too hot or too cold. Alcohol and smoking slow down the healing process and can increase the pain. After treatment your face may be painful and swollen. This is normal and can continue for up to 5 days after treatment. To reduce any swelling, put a few ice cubes in a plastic bag and place it in a flannel. Hold the it against the face, at the place where you were treated. Do not cool your face down too much, because the swelling may increase. Any pain can be counteracted with Paracetamol (preferably not aspirin). Paracetamol can be obtained from all chemists.

In some cases the wound will have been sutured closed. The thread used will dissolve automatically unless the dentist tells you that this is not the case; you will then be given an appointment for suture removal.

If bleeding does not stop, swelling continues or suddenly appears, there is a ‘throbbing pain’ at the site of the wound, painkillers do not help or your body temperature rises to above 39 °C, please contact us.

Root canal treatment

If you have root canal treatment planned, please read and follow the information below:

Once the local anaesthetic has worn off you can eat and drink again. You might have an unpleasant taste in the mouth for a few days. This is usually the result of the medication left inside the tooth.

Pain can be counteracted with Paracetamol, Ibuprofen or Aspirin. Sometimes the tooth is left open to get rid of any infection. Try to suck on the tooth in question; this will help to get rid of unwanted visitors. Keep the hole open by applying good oral hygiene methods.

At the commencement of root canal treatment, you will usually be given a follow-up appointment. The tooth will then be filled and the treatment completed. Should swelling increase after the root canal treatment, please contact us. If the body temperature rises to 39 °C or more, you should also contact us.

In some cases, the dentist might prescribe a course of antibiotics. You will need to take one capsule three times a day before meals for 5 days. Complete the full course! Even if the pain has gone.


If you have been fitted with a new set od dentures or the old one has undergone rebasing, pressure sores might appear. These are blisters formed at places where the dentures press too hard against the gum. Do not wait to see if it gets better, contact us to make an appointment. We do not have to do much in order to completely relieve you from your discomfort. If you don’t come in to see us, be assured, the pain rarely disappears on its own!


Complaints or side effects to painkillers? Contact the dentist in The HagueThere are many painkillers on the market, but we recommend Paracetamol. Sometimes you will receive a prescription for another type of painkiller.

NB: Please read the enclosed patient information leaflet in the box and do not exceed the specified dose.
