Olive oil at the most will work as a lubricant and soften the wax in the inner linings of the ear; it will not actually help in unblocking the ear as one would have to remove the ear wax manually. Also in case of an ear infection olive oil would actually aggravate the condition and may lead to temporary hearing loss.
A few drops of Tea Tree oil in combination with olive oil has been known to unblock ears and get rid of any ear infections at the same time. It has been observed according to recent research that olive oil as compared to ear drops gives better results without damaging the delicate inner linings of the ear.
Some other methods that may be employed to unblock ears are getting them syringed by a doctor or using an ear candle. In any case it would be always better to check with an ear specialist (otolaryngologist) in case of chronic wax buildup accompanied by pain and hearing loss as it could be the sign of an underlying infection.
