Laravel ID obfuscating (Meaningless Numbers to Meaningful Title)

I am using a Laravel jenssengers MongoDB and it is my first time seeing the word obfuscating. I see many open source options on github but nothing that does what i want.

How do i obfuscate my url from looking like this

http://ift.tt/29g09ez

To looking like

http://ift.tt/29GgU1a

My routes expect an article id like so

Route::get('/article/{article_id}', [
   'uses' => 'MainController@singleArticle',
   'as'  => 'article'
]);
...And Controller
public function singleArticle($article_id){
    $article = Article::find($article_id);
    return view('article',['article' => $article]);
}

And i am assuming it is quicker working with ids rather than text.(Correct me if i am wrong) Therefore changing the route to ...

Route::get('/article/{article_title}', [
   'uses' => 'MainController@singleArticle',
   'as'  => 'article'
]);

and controller to

public function singleArticle($article_title){
    $article = Article::where('title',$article_title);
    return view('article',['article' => $article]);
}

Would be a bad choice that i might regret later when two articles have the same title?

So how do i obfuscate my routes, to look like the title of the article which is being fetched from the database?
