In your case, you need to get all the 4 wisdom teeth removed since all the 4 teeth are impacted (tooth that remains stuck and doesn’t grow properly).
Next Steps
You should visit your nearby dentist and get it removed
Health Tips
No, the infection doesn’t spread to other organs or cause any serious health problems. Only in some cases, the infection can reach your spaces and cause space infection, cellulitis etc. So it is better to get the tooth removed asap, if your overall health is fine with no serious medical history and your dentist gives a heads up to go ahead with the extraction.
