You can submit your Site Map (xml site map) in Search Engine Sites than you will be indexed by Google ASAP. Other way is you can change your content or interlinking the internal pages each other.
I'll prefer you to make your interlinking strong and then submit the sitemap Google. Google will re-index your pages. If you have not changed your contents from long time and it's also preferable to change the content.
