Thanks for sharing your concern.
Third molar is neither esthetically nor functionally important.therefore it is usually advised to get extracted.
In your case, you must take a x ray
which will guide you about the available space in your jaw for eruption of third molar.
After that you can decide whether to get the tooth extracted or not.it is your choice,if you are convinced with enough reasons,only then you should get it extracted.
Antibiotics and analgesics are temporary relief in this case,permanent solution is always extraction.
As this last molar always leads to recurrent infection called pericoronities,due to poor hygiene there.
Hope i have answered your query.
