Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain slight fever along with sores in mouth and eruption of wisdom tooth can be related as inflammation caused during eruption of wisdom tooth and pain can lead to slight rise in temperature of body..
But in case if there is
high fever it can be due to viral infection..
I would suggest that she can take
Acetaminophen for fever..
For mouth ulcers gargle with warm saline solution..
Gargle with numbing mouthwash containing Lignocaine..
Take
multivitamin supplements..
Gargle with antiseptic mouthwash..
Avoid spicy food and drink plenty of water..
In case of no resolution consult a General Physician and get evaluated and he can do a clinical evaluation and also advise you
blood test to confirm the cause and treat accordingly..
Hope this information helps..
Thanks and regards.
