A check-up is easy to plan before the holidays: the child has free time, and you do not have to work around lessons. But if the child has complained of toothache, should you wait for the booked date? Pain on its own does not tell you the cause, or how long it is reasonable to wait. Go by the child's complaints and how they feel, and ask a dentist about the timing.
A routine appointment is right when nothing is bothering the child. If pain has started, the reason for the visit has changed: tell the dentist about the complaint, even if a check-up is already booked for the holidays. Pain and signs of a possible infection are among the reasons to seek dental care described in guidance from the American Academy of Pediatric Dentistry.
Parents do not need to decide which tooth hurts or how serious the cause is. It is more useful to notice when the complaint started, whether it comes back, and whether it stops the child eating, sleeping, or doing ordinary things. Those details help the dentist. They do not replace an examination.
In broad terms there are three choices: keep the routine appointment, contact the dentist without delay, or seek urgent medical care. The choice depends on the symptoms, not on how many days are left before the trip.
If the child is not complaining of anything, a free week is a good time for a check-up and for questions you wanted to ask. A holiday booking should not stay the only plan if pain appears before it.
If a tooth hurt and then quickly settled, that does not explain the complaint. Note when and how the pain started, and tell the dentist if an appointment is already booked. If the pain returns or gets worse, call the clinic and ask whether an earlier visit is needed. General advice on toothache in children is published on HealthyChildren.org.
Do not cancel a booked visit only because the child has stopped complaining. Tell the dentist what happened. They can help you decide what to do with the appointment.
Do not wait for the holidays to start if:

This list does not diagnose the problem or set an exact waiting time. When you call, describe the symptoms and ask when the child should be seen. If the cheek is swollen, do not leave the call until a free week, even if the child cannot point to the tooth.
After an injury, say when and how it happened, what is bothering the child now, and whether you have noticed a change in the tooth or the gum. Do not judge the consequences of a blow by how strong the pain is. Ask the dentist whether an examination is needed, and when.
If a trip is already planned, give the departure date when you call. That helps you talk about how to arrange a visit. It does not replace an assessment of the complaint. Do not assume the pain will have gone, or stayed the same, by the time you leave.
Seek urgent medical care if the child is struggling to breathe, swallow, or speak, if swelling involves the eye or the neck or is growing quickly, or if the child is clearly more unwell. Do not wait for a dental appointment or for the clinic to call back. Difficulty breathing, swallowing, or speaking, together with swelling, is listed among the warning signs in NHS advice on toothache.
If there is pain, a swollen gum or cheek, a fever, or an injury, contact a dentist promptly and ask how urgent the examination is. If the warning signs above are present, the priority is a medical assessment, not waiting for a dental appointment.
Do not try to decide from the outside whether the swelling is “enough” to seek help. When you call, name every symptom at once, and say if the child is struggling to breathe, swallow, or speak, or is getting worse.
Prepare a short account of what you noticed. You do not need medical terms, or the exact cause of the pain. It helps the clinician to know:
If the child cannot describe the feeling or point to the tooth, say so. Report what you saw yourself, and say if the symptoms have changed since the first call.
If the usual clinic is closed, find out where urgent dental care for children is available. Do not automatically move the call to the day the clinic reopens. If the signs that need urgent medical care are present, seek that care. Do not wait for a dental appointment.
While you are arranging an examination, watch how the child is. If there are new complaints or they are worse, say so when you call again. If breathing, swallowing, or speech is difficult, or the swelling is growing quickly, do not wait for the dental clinic to reply.
The note helps you choose the next step. It does not replace a clinician's assessment. If a complaint appears after a routine visit was booked, tell the clinic: a time chosen for prevention may not be the right time for a child in pain.
Pain going away does not explain why it started. If a visit is already booked, tell the dentist about the complaint before you cancel. If the pain returns or gets worse, ask whether the child should be seen sooner.
Do not put off calling if the pain does not settle, keeps coming back, gets worse, or stops the child eating and sleeping. Also report a swollen gum or cheek, fever with the pain, and any injury. After hearing the situation, the clinician can say when an examination is needed.
Contact a pediatric dentist without delay and describe the swelling and the other symptoms. If the swelling is growing quickly, involves the eye or the neck, the child is struggling to breathe, swallow, or speak, or is clearly more unwell, seek urgent medical care.
If the usual clinic is closed, look for urgent dental care that will see children. When you call, describe the pain, the swelling, any fever, and any injury. If the signs that need urgent medical care are present, do not wait for the dental clinic to open.
