Hello
The headache as you said can be because of offending tooth.
You need to get a video consultation done or try a physical consultation for better understanding of your problem.
Removing a tooth which is not worth saving is absolutely fine as it will not cause any problem in future if you are getting it replaced . If after removal you are not getting it replaced thn other teeth might start troubling you in future.
We are open for video Consultataion if you want to get it done.
